AC R134A pressure topped up to 40psi. Vent thermometer went from 46-48F to 40F right in the middle of the green zone 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. ## Features - Waterproof ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002G1PBHI | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #226,338 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #37 in Thermometers (Car & Motorbike) | | Brand | A/C Pro | | Brand Name | A/C Pro | | Colour | White | | Customer Reviews | 4.6 out of 5 stars 1,450 Reviews | | Display Type | Analog | | Global Trade Identification Number | 00048168028030 | | Immersion Depth | 5 Inches | | Included Components | InterDyn - TH-27 | | Indoor Outdoor Usage | Outdoor | | Item Length | 7.87 Inches | | Lower Temperature Rating | 17 Degrees Celsius | | Manufacturer | Interdynamics | | Model Name | InterDyn - TH-27 | | Model Number | TH-27 | | Outer Material | Glass | | Outer Material Type | Glass | | Part Number | TH-27 | | Power Source Type | Manual Winding | | Product Care Instructions | Wipe Clean | | Resolution | PT is: THERMOMETER.
