Meanwhile, the base unit also shows the information, so it’s simple to glance at it when the cook is near the grill. We particularly liked the design of the base, which was quite easy to read. The included color-coded probe rings make it easy to see which probe belongs to each temperature reading on the base. For cooks who don’t like apps, the base unit can easily be used without the app. This is available in multiple colors to match the décor or stand out from the crowd. The clear plastic cover for the charger/signal booster is also a nice touch and helps keep the rain out when you’re cooking outside. The ambient temperature sensor that is located in the ceramic handle is responsible for measuring the cooking chamber temperature. Remove the probe from the charger and press the add device button and the app will connect automatically to the probe. The Signals thermometer includes four probes—three are high-temperature cooking probes and the fourth is for measuring air temperature inside the grill or other cooking chamber. The app allows remote monitoring of the temperatures using both Bluetooth and Wi-Fi, so there are no worries about getting out of range of the base. It recharges via a USB cable/power plug and can run while it's plugged in, which is great if there's a very long cook.

This makes it difficult to gauge how far to insert the probe into your meat to find its thermal center. I want this completely wire-free technology to work, but I think it’s halfway there with just one of the two temperature sensors that are trustworthy. The ambient temperature sensor located in the handle of the TempSpike is definitely its worst feature. There are variables that can affect these readings such as probe placement in the meat and the location of the heat source so it is difficult to draw definitive conclusions about which probe is the most accurate. Best Feature- The internal temperature sensor is accurate, partially helped by its placement near the tip of the thermometer.If you’re using a thermometer with a rechargeable battery (like the MEATER), it’s important to always return it to the charger when after each use. The last thing you want is to reach for your meat thermometer when you need it most, only to find the battery has died. For thermometers that require disposable batteries, be sure you always have extra so you don’t run out mid-cook. And, as with all gadgets (especially ones you use for cooking), store all of the components together.

The ThermoPro TempSpike is a completely wireless Bluetooth meat thermometer with a good signal range thanks to its signal booster/charger. The significance of this sensor placement is less pronounced when you’re using these types of probes for larger pieces of meat over extended periods of time. If you're willing to give up some of the TP20's more advanced features, such as presets, ThermoPro also offers its TP08S Digital Wireless Meat Thermometer, which has the same wireless range and temperature range but costs a little less. The TempSpike has two thermometers integrated into its design. There is the tip of the probe (the side inserted into meat) that will measure the internal temperature of your food. There is also a thermometer on the end of the probe that will measure ambient temperature during your cook.We thoroughly tested this twice, and it's hard to find any faults. The two thermometers in one probe proved accurate at reading internal and external temperatures, while the app proved unique tones and a wide range of alarms. One issue was the Bluetooth range didn't hold up to the full range due to regular suburban obstructions, and once the signal was lost, it took a few extra beats for it to reconnect to the phone. That’s why every instant-read meat thermometer and every conventional temperature probe has a temperature sensor located in the tip.
