ThermoPro TempSpike Twin (TP962)

This page covers the TempSpike Twin TP962, the model with two probes, not the TP960 with one probe. Under ASIN B0C39YHDHQ the Amazon catalogue shows the model number TP962 and the part number TP962W, and the manufacturer sells the Twin TempSpike as the TP962. The delivery includes two wireless probes and a charging station that TempPro calls the booster: it has a backlit LCD, charges the probes and relays their readings to your smartphone. Our product photo shows exactly this combination too. We discuss the TP962 and bring in the TP960 only where the two differ.

ThermoPro is now called TempPro. According to the Amazon listing, the company structure and products stay the same, and with random shipping you may receive either a device with ThermoPro or one with TempPro lettering. On Amazon the TP962 cost approx. €63 on 05.10.2026. The other wireless and wired thermometers we compare are collected in the grill thermometers category.

TP962 and TP960: same measuring technology, different booster

Both measure in the same way. According to the manufacturer, each probe has one sensor for the core and one for the ambient temperature, and TempPro names NTC as the sensor type for both models. The measuring ranges are identical, and at the core the manufacturer quotes ±1.0 °C for both. The differences lie in the number of probes, the booster, the runtime and the wireless ranges.

The TP960 has one probe and no screen; TempPro describes it as fully app-based. Its manual shows three indicator lights on the booster: one for the probe battery, one for the booster battery and one for the connection, which flashes green as long as the probe is reachable and red as soon as contact is lost. A single probe with a display on the booster is, according to TempPro, available in the TP971 with LCD.

On probe runtime the TP960 is ahead. According to the product page its probe lasts 48 hours or more, its booster about six days, and 15 minutes of charging should be enough for 2 hours of probe operation. Its booster, at 170 x 47 x 27 mm, is also slimmer than that of the TP962.

The names are confusing. The first Amazon bullet point calls the TP962 “TempSpike PLUS”, and that is also what its manual’s title page says, with the print code 962-V20260422. The TP960 manual, by contrast, is titled “TempSpike CORE”. Despite the name, the TP962 differs markedly from the TempSpike Plus TP970 and the Twin TempSpike Plus TP972, among other things in the probe’s heat limit.

What is in the box and how the booster works

According to the Quick Start Guide there are seven items: the probe with the black handle, the probe with the white handle, the booster, a cover, a USB-C charging cable, a cleaning brush and the quick guide itself. You supply a USB power adapter yourself; the manual says to connect the cable to any USB charger.

The probes are made of stainless steel, heat-resistant and food-safe according to the manufacturer, and waterproof to IP67 according to the manual. They are built to stay in the meat for the whole cook. Each has a built-in 2.4 V lithium battery.

The booster receives the signals from the probes, relays them to your smartphone and charges the probes while they sit in their slots. It has its own 3.7 V lithium battery and a USB-C socket. Two built-in magnets hold it, according to the manual, to a grill, oven, smoker or other metal surfaces. TempPro gives its dimensions differently in two places: the product page says 170 x 58 x 26 mm, the manual 174 x 62.5 x 26 mm.

The LCD measures 48 x 16 mm. It shows the temperatures of both probes and their battery levels, plus a bell when the alarm on the booster is switched on and a crossed-out bell when it is off; you can toggle this in the app settings. When both probes are fully charged, the display switches off.

Below the display are two buttons. The one with the sun symbol switches the backlight on and off. The one with the S has five functions according to the manual: one press switches the booster on. During operation it switches the display between core temperature, ambient temperature and automatic alternation, and it also silences the alarm. Held for three seconds it pairs booster and probe, and held for ten seconds it resets the booster, provided both probes are out of their slots. Booster and probes are already paired with each other from the factory.

In detail: NTC sensor, insertion depth and heat limit

An NTC sensor is a thermistor. As it gets warmer, its electrical resistance falls, and the electronics convert the resistance into a temperature. The TP962 probe records the core from minus 10 to 100 °C and the ambient temperature from minus 10 to 300 °C.

For accuracy, TempPro quotes ±1.0 °C between minus 10 and 100 °C, so across the entire core range. Outside that, ±2 % applies. If you read the percentage as a share of the measured value, that is up to 5 °C at a cooking chamber temperature of 250 °C. What one degree at the core means is shown by our core temperature chart: poultry needs at least 72 °C there, and at ±1.0 °C a core that the display reports as 72 °C may in reality be at 71 °C. An alarm at 73 °C keeps a margin to the minimum temperature. A medium steak is at 55 to 57 °C in the chart: if the TP962 shows 56 °C, the actual value may, according to the manufacturer, lie anywhere in that window.

More than the one degree, the insertion depth counts. The manual makes it the first of its warnings (wording in the section on care and safety), and the product page describes the mark as a depth ring near the handle: the probe should be inserted at least that far, or so far that only the handle sticks out, otherwise it can be damaged. TempPro does not state how far the notch and depth ring are from the tip. If the ring is near the handle, however, by our reading a piece has to take up most of the 132 mm long probe, which is 6.5 mm thick. You insert the probe into flat steaks horizontally from the side, and they must be wide enough for that. For thin pieces TempPro offers the Twin TP963, which comes with a long and a short probe.

The second limit concerns the cooking chamber. As the maximum ambient temperature, TempPro lists 300 °C (572 °F) for the TP962 in its comparison table, and for hot searing and very hot smokers the manufacturer refers to the TP970 and TP972 on the TP960 page. For steaks, reverse sear suits the TP962: first indirectly with the probe inserted until just before the target, then pull the probe and sear briefly over the embers. How to set up two zones for this is explained in the guide to direct and indirect heat.

Does the wireless connection reach from the grill into the house?

In open space, yes: TempPro quotes up to 150 m between booster and smartphone. Through walls it is less. It gets tight on the short stretch from probe to booster, because a closed metal lid shields the probe.

For this stretch, according to the manual, the connection usually reaches up to 140 m outdoors. With the probe inserted in a closed metal cooker it drops to 4 m in the worst case. A kettle grill with its lid on or an oven with the door closed is exactly this case, and a booster on the garden table a few steps away may then already be too far. Where it belongs instead is given as point 4 in the section on care and safety.

From the booster to the smartphone the TP962 transmits via Bluetooth 5.2, according to the product page up to 150 m (500 ft) in open terrain. The manual ties this figure to an ambient temperature of 25 °C without obstacles and without electromagnetic interference. Metal lids and the food itself additionally shorten the range according to the product page. Wi-Fi comes in the series only with the TP980. On the Apple Watch the app also shows temperatures and alarms, according to the product page.

The magnets invite you to stick the booster to the grill wall, and the manual expressly names the grill as an adhesion surface. The TP960 manual forbids heating the battery above 60 °C; whether the wall of a running grill gets that hot, we do not know. We would therefore attach the booster to the cart or frame rather than to the lid or firebox.

App, alarms and battery

According to the Quick Start Guide, the TP962 is set up in this order: download the “TempPro” app, switch on Bluetooth, fully charge booster and probes, take one probe out of the booster so that its temperature appears on the display, and in the app scan the QR code on the back of the booster or choose “TempSpike” from the list. After that, the TP962 is added in the app and connected to the TempPro cloud.

Before cooking you insert one or both probes and choose a target temperature or type of meat and doneness in the app. For each probe you can also set a highest and a lowest ambient temperature. When a value is reached, the app, the booster or both alert you, depending on the setting. The display shows the current values even without a smartphone. Target temperature, meat presets, cooking curve and push alarm, however, are available only in the app according to the product page; for a target alarm you therefore have to open it at least to set it up.

We consider the cooking chamber limits the more useful half of the alarms. A lower limit reports a dying fire while you can still add fuel, and an upper limit just below the limit of the ambient sensor warns you before the probe gets too hot.

After a full charge the probe runs 36 hours or longer according to the product page. For a 5 kg packer, our brisket guide allows 8 to 14 hours of cooking time, which one charge covers with reserve. For the booster, the manual and Amazon give about 5 days, while the product page says 3 months or more. The contradiction remains open; as a planning figure, the shorter value is the safe one. Charging happens in a chain: the USB-C cable charges the booster and the booster charges the probes in their slots.

Care and safety according to the manual

Under “Caution” the TP962 manual lists seven points, here in our translation:

1. The probes contain sensitive electronics. To keep extreme heat from damaging them, always insert the probe into the meat far enough that the notch is completely covered by the meat.
2. Clean the probe tip thoroughly after each use; deposits on the charging contacts can prevent the probe from charging properly.
3. Do not use the device in the microwave.
4. The connection between probes and booster usually reaches up to 140 m in open terrain, but can shrink to 4 m when the probes are in the meat and the metal cooking appliance is closed. During cooking, therefore, place the booster as close to the probes as possible, for example directly outside the cooking appliance, always watch whether the connection between probes and booster drops, and in that case move it closer.
5. Always pull the probes out of the meat with a glove after cooking.
6. Wipe the probes with a kitchen towel or cloth after each use. Rinsing and the dishwasher are also permitted.
7. After cleaning, always put the probes into the booster for charging and storage.

The TP960 manual warns of the same things in six points, but names only rinsing instead of the dishwasher: only once the probe is back at normal temperature, and never while it is still hot, because that can damage the device.

Only the TP960 manual has its own section on the lithium batteries. It warns of fire, explosion and burn hazards. The battery must not be opened, crushed, punctured or taken apart, not short-circuited, not exposed to water and not heated above 60 °C or burned; charging is only with the specified charger and according to the manufacturer’s instructions, a damaged or swollen battery stays unused, and disposal follows local regulations. Lithium batteries are also in the TP962; we therefore read the list as a notice for both devices.

According to the manual, you must not dispose of the TP962 with household waste, but via an approved collection point or the local recycling centre; current regulations apply, and if in doubt you ask your municipality. In the same manual TempPro declares conformity with the Radio Equipment Directive 2014/53/EU and the EMC Directive 2014/30/EU.

What is missing from the documents

We did not find the following, neither on the product page nor in the Quick Start Guide or the Amazon catalogue:

• the weight of probe and booster and the material of the booster housing;
• a protection rating for the booster (the IP67 figure expressly applies to the probes) and the temperature it withstands at the grill;
• the battery capacity in mAh and the charging time to a full charge;
• a separate accuracy figure for the ambient sensor;
• what the connection to the TempPro cloud does, for example whether you can see readings outside Bluetooth range;
• a German manufacturer shop or a euro price from the manufacturer; TempPro itself sells only in US and Canadian dollars;
• an EU declaration of conformity for the TP962 and the importer in the EU (the manual refers to a page on which no declaration for this model appeared on 2 October 2026; the declaration for the TP960 dated 30 September 2022 names Shenzhen Ecare Electronics Co., Ltd. as the manufacturer).

Three alternatives from our catalogue

The prices are guide values from the price fields of our review pages with differing dates, and the shop may show a different amount. The score is our editorial assessment based on manufacturer data; we have not handled any of the four devices.

Who it suits: when the TP962 fits and when it does not

First, what counts is how many pieces cook at the same time. Two probes suffice for two pieces or for two measuring points in a large one. For a whole packer brisket we consider two measuring points sensible, because flat and point finish at different speeds. If two probes are not enough, the Inkbird IBT-4XS is the alternative from our catalogue, €3 cheaper by our guide values. Its cables, however, run through the lid or door, Inkbird quotes 0 to 250 °C for continuous operation, and according to Inkbird the base transmits up to 46 m.

The TP962 becomes unfavourable when two cookers run in different places, for example a roast in the oven and a chicken in the kettle grill on the terrace. A single booster would then, according to the manual, have to sit close to both probes, and that only works if both appliances stand next to each other.

Among the devices compared here, more heat reserve (MEATER 2 Plus) or a tighter core value (MEATER Plus) comes only at a premium. The MEATER 2 Plus costs €55 more by our guide values, almost double, and in return has only one probe and no display. The MEATER Plus costs around €12 more and, according to MEATER, tolerates an ambient temperature of only 275 °C, less than the TP962. Our assessment: if you do not need to cook to the half degree, you gain little with the MEATER Plus and give up the second probe and the display on the booster.

The wrong choice, the TP962 is for anyone who mainly grills sausages and thin steaks directly over the embers. Such pieces barely take the probe up to the depth ring, and for hot searing with the probe inserted TempPro itself refers to other models. For them, an instant-read thermometer with a thin needle that is only briefly in the meat for measuring is the better fit; which design suits which purpose is covered in our guide to grill thermometers.
