L302 HVAC Vacuum Pressure Temperature Tester Leakage Test Refrigeration Tools Digital Manifold Gauge Meter

* Three modes:refrigerant pressure mode,vacuum percentage mode, leak detection mode. * Real-time vacuum pressure test and percent indicate. * Pressure units: KPa,Bar,PSI,InHg,KgF/cm2 * Temperature units: , * Test range: 0 KPa~6000 KPa * Resolution: 1KPa * Accuracy: ±0.5% * Overload: 10MPa * Operating temp: -20~60 * Auto power off function:10min(POWER ON/OFF switchable,default POWER ON). Product Features: *[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 Interface] L302 AC Refrigeration Tester double 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. WORKING MODES The system comes with three common working modes: refrigerant pressure mode, vacuum percentage mode,leak detection mode. The interfaces of different working Application: Suitable for installation, testing and maintenance of refrigeration equipment such as air conditioners, refrigerators, and cold storage.
