Dual Probe ThermoPro Thermometer

Adding a thermometer to your coffee roaster is a great DIY hack. Having 2 probes allows you to (for example) have one directly probing the mass of roasting coffee beans, and the other to check the roast chamber air temperature (or input air temp ... or output air temp etc). This is similar to how commercial roasters check coffee roasting temperatures, by comparing and monitoring bean temperature, to "environmental temperature".

Exactly how you want to use the ThermoPro, and how you will install it, is going to be up to you. But when we were checking out options for a thermometer that can measure 2 temperature points at once, it was a meat thermometer that stole the show. ThermoPro has great reviews, and the temperature range it can measure works great for coffee roasting. The 15 cm long metal probes are less sensitive than raw thermocouple beads, but are easier to postion and last longer! It's a well-built device, and the AAA battery is included to boot. (Remember to peel the plastic wrap off the batter first though!)
