The Digital Manifold Gauge Set HVAC has built-in 90 kinds of refrigerant data（American NIST standard）and including common refrigerant types such as R22, R32, R134A, R410A, etc. The three working modes are frigerant measurement mode, vacuum measurement mode & leak detection mode Compatible with air conditioners, fridge and cold storage. Three Common Working Modes 3 Working Modes: refrigerant measurement, vacuum measurement mode & leak detection mode. The HVAC gauge built-in 90 kinds of refrigerant date, including refrigerant types such as R22 R32 R290 R410A. Refrigerant Visible Window There refilling status of the refrigerant can be observed through the visual window, which let your work proceed faster and more accurately. Intelligent Digital Display Short press the power key to adjust the brightness, which the data display is clear and easy to read. Support Multi-Unit Switching Multi-unit pressure and temperature conversion can be performed according to requirements. Pressure Units: KPa, Bar, PSI, In Hg， KgF/cm2 Temperature Units: ℃, F Vacuum Measurement During the process of vacuum extraction in refrigeration system, the vacuum degree and vacuum pressure can be accurately measured. The higher the percentage, the higher the vacuum. Leak Test of Refrigeration System It can display the current pressure, leak pressure, and detection time of the refrigeration system in real-time, so as to judge the status of the leak (refrigeration system) more intuitively.
