AUNMAS Refrigeration Digital Vacuum Gauges, 0KPa to 6000KPa 5 Units (KPa, Bar, PSI, InHg, KgF cm2) HVAC Vacuum Pressure Gauges for AC Fluoridation

Spec: Item Type: Digital HVAC Gauges Working Mode: Coolants measurement mode, vacuum measurement mode, leakage measurement mode, can measure the percentage of vacuum degree Pressure Unit: KPa, Bar, PSI, InHg, KgF/cm2, Temperature Unit: ℃, ℉ Pressure Measurement Range: 0KPa~6000KPa, Resolution: 1KPa Sensor Accuracy: ±0.5%, Overload Limit: 10MPa Operating Temperature Range: -20℃~60℃ Automatic Shutdown: 10min(can be set to start or close, default start) Battery: 1 x 9V 6F22 battery(not include) How to Use: 1. Please follow the operating guide or the guidance of professional personnel. 2. The digital display should be kept clean and the screen should be bright and clear, so that the values such as pressure and temperature on the display screen are clearly visible. Use a weak shells cleaner or soapy water to clean the display shells and copper joints regularly. 3. Pressure gauges are vulnerable parts and should be sent to the measurement department for regular calibration to ensure accuracy. 4. Handle with care when using, to prevent shock and dropping. 5. After use, please turn the knob to the OFF position to extend the life of the valve spool. 6. For unused digital displays, it is best to block the interfaces of each joint to prevent foreign objects from entering. Regularly purging and replace the coolants pipe, and clean the impurities in the valve body. Package List: 1 x Digital HVAC Gauges
