The Predictive Thermometer (CPT) has 8 sensors, the most of any wireless thermometer.
7 sensors are spaced equally along the length of the “probe” and the 8th sensor is placed in the handle to measure the ambient temp near the food (more about that below).
It shows you all the temperatures from the surface to the center (and the external “boundary layer”) for the duration of the cook. This “Total Temperature Awareness™” means you know how evenly your food is cooking, how things are changing, and when exactly it will be done to your exact specified temp.
You eat more than just the center of the food. So you need a thermometer that measures all the temperatures!
The CPT was the first thermometer to put multiple internal sensors (TrueCore™ Sensors) into the tip. Those “extra” sensors let the CPT find the lowest internal temperature even if you missed the mark.
It’s also the ONLY thermometer that has the ability (and the sensor placement) to measure the true cooking temperature at the surface of the food (TrueSurface™ Sensors). Pay attention to that temperature! It’s the secret to consistent, precision cooking.
The temperature at the surface of your food is the best measure of heat being applied.
The surface is nowhere near as hot as the surrounding oven - that's because your food sweats. As it does, the evaporating juices cool the surface to a lower cooking temperature.
How much? It varies, and that's why we measure at the surface.
By measuring surface temp, you can adjust your oven or smoker to control the true cooking temperature, bringing a precision to your cooking that was previously only possible with sous vide.
The CPT is also the only thermometer with onboard processing. This may seem like a nerdy call-out, but because we have a tiny computer in the thermometer itself, doing all the intensive cooking math, it’s far more reliable.
All other wireless sets outsource the thinking to a second device, whether that’s a phone or a base station of some kind. So your data (and therefore your cooking outcome) is dependent on a continuous connection between their dumb probe and the smart device. That introduces multiple points of failure.
