Review on 🌡️ DURAC Bi Metallic Thermometer 125F B61310 3100: Precise Temperature Measurement for Accuracy by Erik Barela

I use it to measure the temperature of our mobile home battery in its plastic battery housing. I drilled a hole in the battery compartment so the probe would go in the box and run alongside the battery. The hole size is slightly smaller so the thermometer doesn't move when you move it. I record the temperature in the morning before the sun hits the box and know that together with the battery voltage I can estimate the remaining battery capacity.
