Hello everyone. I have Herpstat for my rack and have the probe in contact under the heat tape. My question is what is a good and affordable thermometer to check the hot spots in each tub. I have two cheap amazon infrared thermometer. A Nubee and etekcity. They are CRAP! Not accurate at all. Anyone have an opinion about thermometers and which one to get. I really don’t want to spend $150 on a fluke if I can help it. Thanks for your time.
