HVAC Refrigeration Digital Manifold Gauge Vacuum Dual Pressure Temp Leak Tester. MRCARTOOL Digital refrigerant gauge. Adopts the most advanced digital circuit and the high precision pressure sensor, used for both high accuracy refrigerant pressure and vacuum pressure, build-in 90 refrigerants according to NIST standard refrigerants pressure and temperature relationship database, real-time test of pressure got relative temperature which can help you more convenient for refrigeration system installation or servicing. The pressure of the low-pressure pipe and high-pressure pipe can be tested in refrigeration system. Blue arrow “LOW” for low pressure rotary switch, red arrow”HIGH” for high pressure rotary switch. The temperature of the low-pressure pipe and high-pressure pipe can be tested in refrigeration system. The refilling status of the refrigerant can be observed through the visual window. And high-quality dual-table valve with high precision pressure sensor, excellent workmanship, stable performance, Large screen, display data clearly. The brightness of the screen is adjustable, so it can be used even in a dark environment. Universal function button, only one side of the buttons can control two dials at the same time, which is convenient for the left and right hand operation. Three Common Working Modes. Refrigerant measurement mode, vacuum measurement mode, and leak detection mode. During the process of vacuum extraction in refrigeration system, the vacuum degree and vacuum pressure can be accurately measured. Mrcartool L302 digital refrigerent is suitable for testing and maintenance of refrigeration equipment such as air conditioners, fridge and cold storage. 1 x L302 HAVC Manifold Gauge. 3 x Manifold Gauge Hose. 2 x Adapters (2 sizes). 1 x User Manual.
