Review on 🌡️ Supco ST02 Pocket Dial Thermometer - Stainless Steel, 5" Stem, 1" Dial, 0-220°F by George Jacobson

I don't know why I bought this - my skin was calibrated in South Florida over 50 years ago so I can put my hand on the car vent and tell whether I'm getting it 40 degrees. But some people still don't believe me. Regardless, this is the classic, small, inexpensive analog pen and pocket thermometer that HVAC professionals have used for years. If you are not sure whether your car air conditioner is working well, the first thing I will say is that I do not know what is wrong with you. how could you not say But I guess not everyone has my rare superpower. In that case, you should buy this - stick it in your car's air vent and confirm or dispel your suspicions.
