L302 HVAC Digital Manifold Gauge Set, High-Precision R12 R134A R410A etc. [Working Principle] Digital Manifold Gauge Set HVAC adopts the most advanced digital circuit and the high precision pressure sensor. They are well made and accurate(Accuracy: ±0.5%), used for both high accuracy refrigerant pressure and vacuum pressure, which can help you more convenient for refrigeration system installation or servicing.
[Double Display Interface] L302 AC Refrigeration Tester double display interface is designed for dual pressure test(high and low pressure) and dual temperature test. The pressure and temperature of the low-pressure pipe and high-pressure pipe can be tested in a refrigeration system. Blue arrow"LOW" for low-pressure rotary switch, red arrow"HIGH" for high-pressure rotary switch. [Three Working Modes] The system comes with three common working modes: refrigerant pressure mode, vacuum percentage mode and leak detection mode.You can select the corresponding measurement mode according to your need. This is good tool HVAC and refrigeration technicians. [Built in 90 Refrigerants] L302 digital manifold gauge built-in 90 refrigerants and corresponding temperatures sheet data according to the US NIST standard.
