Specification: Item Type: Digital HVAC gauges Material: ABS, Aluminum Alloy Working Mode: Freezing medium measurement mode, vacuum measurement mode, leakage measurement mode can measure vacuum percentage. 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℃ Auto Shutdown: 10min (Can be set to start or stop, default start.) Battery: 9V 6F22 Battery x 1 (Not Included) How to Use: 1. Follow the manipulation guided or the guidance of a professional. 2. Keep the digital display clean and the screen bright and clear to ensure easy visibility of pressure, temperature, and other numerical values. Regularly clean the display shells and copper joints with a cleaner or soapy water. 3. Pressure gauges are vulnerable components and should be periodically calibrated by the metrology department to ensure accuracy. 4. Handle with care to prevent impact and falling. 5. After use, turn the knob to the OFF position to prolong the valve core's lifespan. 6. When not in use, it is recommended to seal the joints of the pressure gauges interface to prevent foreign objects from entering. Regularly blow and replace the freezing medium pipe, and clean the valve body of dust and impurities. PackageList: 1 x Digital HVAC gauges
