Review on Comark PDQ400 Waterproof Pen Style Digital Food Thermometer: Ensuring Accurate Rinse Temperature in Commercial Dishwashers - Blue by Sharon Fuller

Accurate and fully waterproof. 32 degrees in ice water and 212 in boiling water. I cover the whole thermometer in dish soap and wash it in hot water after use and no moisture gets in. I'll say it's not the fastest, but it does the job. I would prefer high accuracy and stable performance to a few seconds gain and a precise device. Lavatools is a few seconds faster but not as accurate. It should also be noted that the device has a calibration function and a self-calibration cycle that may be carried out automatically. Finally, a spare battery is included.
