Review: A must have for diagnosing automotive and residential AC systems. Works great. - I'm really pleased with this automotive thermometer that I use for checking my work when I repair automotive AC systems. It's pretty self-explanatory with how it works but you just stick it in whichever vent is blowing air to see the temperature of the air. I just reference google to see what the AC temp should be when I start refilling the system with refrigerant. This could also be used in residential HVAC systems. I prefer this style thermometer over a laser thermometer because these are more accurate and it's easy to get an incorrect reading with a laser thermometer. This thermometer was a great value and is a must for any mechanic.
Review: Good to Use to Keep Check on Refrigerator and Freezer Temperatures - We received them in good condition and on time! We bought several to check temperatures in all of our refrigerators and freezers. They work well. They will help us to know if the temperatures deviate from normal.
