FAQ: Predictive Thermometer (2nd Generation)Updated 2 months ago

What's in the box?

• Second generation Predictive Thermometer with charging/standby case

What changed with the 2nd generation Combustion Predictive Thermometer?

A more durable, fully hermetic seal and higher maximum temperature range.

Using high-temperature ceramic-to-metal brazing, we create a true hermetic seal between the ceramic handle and steel tube. Unlike conventional seals or adhesives that can degrade over time, this brazing process creates a permanent metallurgical bond at the molecular level. 

The result is a completely hermetic seal that's tested to IP69k standards – the highest ingress protection rating available.

Key improvements:

• True hermetic seal - safe for vacuum sealing, sous-vide, and deep-frying
• Extended temperature range - high-temp region now reaches 900ºF (482ºC), up from 600ºF
• Enhanced sensor performance - relocated ambient sensor provides faster, more accurate readings
• More durable construction while maintaining all original smart features.

We also introduced built-in WiFi to the second generation accessories (WiFi Display, WiFi Booster, Giant Grill Gauge).

Does this mean the old ones are obsolete?

Not at all! If you have an original Predictive Thermometer that's working great for you, don't worry!

We'll continue supporting it with new app features and firmware upgrades, just like always. And your 1st gen Combustion Predictive Thermometer (CPT) even works with 2nd generation WiFi accessories. Just add one (WiFi Display, WiFi Booster, or Giant Grill Gauge) to your existing set to take advantage of your home WiFi network and watch your temps remotely from anywhere.

The 1st gen Predictive Thermometer is still fantastic for most cooking setups. While the original design performed well overall, we saw an opportunity to improve the durability of the main seal. Our second-generation design uses high-temperature ceramic-to-metal brazing to create a permanent, hermetic seal between the ceramic handle and steel tube.

The 2nd gen CPT offers enhanced durability, improved ambient temperature sensing through a relocated sensor, and an extended temperature range, now reaching 900ºF in the high-temp region (up from 600ºF).

For most everyday cooking applications, the 1st generation CPT continues to work great.

What about WiFi?

Any Combustion Predictive Thermometer (CPT) can be used with any of our new WiFi accessories (WiFi Display, WiFi Booster, Giant Grill Gauge) to connect to WiFi and send live cook data to anywhere in the world with internet access. Be sure to get the newest firmware to use this feature!

WiFi's higher transmission power (more than 10x that of Bluetooth) allows for excellent coverage throughout your home and, through your network, anywhere with internet access. This is especially useful when cooking from your basement or other locations where lower-power signals might struggle.

Why isn't WiFi in the thermometer itself?

It comes down to optimizing battery life while maintaining performance. WiFi draws significantly more power than Bluetooth, and the thermometer's battery must be small enough to fit near the probe tip. By using Bluetooth's energy-efficient design, we can achieve industry-leading battery life (over 92 hours) while still maintaining rapid data updates - every 5 seconds during normal cooking, and up to 5 times per second when it matters most.

Using a separate tool for WiFi connectivity means the thermometer can dedicate its power to what matters: collecting data, calculating predictions, running algorithms, SafeCook™, and all the other features that make the CPT special. 

This design choice helps us maintain the longest functional battery life of any wireless thermometer, even while processing more data than our competitors.

Anything else I should know?

Oh my yes.
