The Bar-B Chek by Maverick is a specialized electronic thermometer designed to keep track of the temperature inside your grill or smoker. It comes with a special smoker/pit probe, will calculate current and average temperature, and will alarm if your smoker becomes too hot or too cold. All you need to do is program the temperature you want your smoker to remain and sit back and listen for an alarm! It really takes the worry out of smoking. The Bar-B Chek also includes a count-down or count-up timer and several mounting options.
