Certified A/C Pro Car Air Conditioner Test Thermometer, Helps Diagnose AC Performace and Checks Outlet Duct Temperature and Ambient Temperature, Includes Holder and Clip, InterDynamics

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.

works well

Excellent, very easy for use, Thank you.

Works decent enough. The numbers can be a little hard to see for old eyes!

This is helpful for diagnosing AC problems. It reads accurate. I like the analog style because it doesn’t need batteries. It fits nicely in my pocket protector too.

Good to have when charging your cars A/C or just to check the current temp.

Easy to use

Although the glass is small and can be difficult to read for some, it is accurate. After recharging my ac, I placed the stem portion into the dach vent and got my ac temp readout! Appears well made and although it's only a one inch dial face, it gets the job done!

Just topped up my Nissan Note E11 diesel AC with this in the vent. AC R134A pressure topped up to 40psi. Vent thermometer went from 46-48F to 40F right in the middle of the green zone
