Description
Features: Package includes: digital vacuum gauge, portable tool bag, brass expansion connector, user manual Sensor cleaning: During the procedure, it is possible that the sensor is polluted by foreign matter, and then you need to clean the sensor follow these instructions: 1. Turn off the vacuum gauge, and remove all the batteries 2. Shake out the foreign matter 3. Using an eye dropper or a syringe fill the sensor chamber with alcohol or isopropanol, tighten the copper cap and then rinse the sensor chamber for 3-4 times with alcohol isopropanol 4. Thoroughly dry the sensor by vacuumization or at least 2 hours of air dry 5. Inspect the vacuum meter and make a Zero Calibration Specification: Connection: 7/16-20 UNF(1/4"Flare) Maximum overload pressure: 14 PS1/ 0.1 Mpa Range: 0-10000Pa, 0-100.00mBar, 0-75.000mmhg, 0-75000Micro Resolution: 0.01(<10Pa)/0.0001(<10mBar)/0.0001(<10mmhg)/1(<30000 μmHg ), Accuracy: 2-100Pa: ±5% of reading(at 20°C) Operating temperature: 0-50°C(32-122°F) Connection: 7/16-20UNF(1/4'' Flare) Note: 1. Measure the vacuum level according to the instructions and within the parameters specified in the manual 2. Do not use any corrosive cleaners or any solvents to clean the department 3. Please Wear goggles and protective gloves before operation it. 4. Tighten the copper cover and store it in a dry place 5. It cannot be used for measurements in non-atmospheric environments (the readings in refrigerant or other gas environments will be inaccurate. If measured in a non atmospheric environment, the accuracy will return to normal after it is placed in the atmosphere for 24 hours) 6. Professional use only. Need a vacuum chamber and a 0.1Pa standard diaphragm vacuum guage are required to complete the zero calibration. Zero calibration will be completed before shipment to ensure the accuracy of each vacuum gauge

Features
- Wide Measurement Range and High Accuracy: equipped with a high-sensitivity sensor, this digital vacuum gauge delivers accurate readings from 75, 000 μmHg (atmospheric pressure) down to 0 μmHg; With a precision of ±10 μmHg or ±10%, it is ideal for leak detection and evaluating evacuation quality in HVAC and refrigeration systems; Resolution reaches 1 μmHg under 30, 000 μmHg, ensuring reliable performance even in high-precision tasks
- Smart App Alerts and Offline Recording: stay in control even when you're away from the product; Connect to the app for real-time alarm notifications, data monitoring, and offline recording; The built-in temperature compensation ensures that your vacuum readings remain accurate under varying environmental conditions
- Dual Calibration Modes: supports both full-scale and zero calibration for lasting accuracy; To calibrate under atmosphere, hold “SAVE/CAL” for 3 seconds until “------” appears; For zero calibration, connect to a vacuum system, wait for 0.1 Pa, then hold “SAVE/CAL” until “0.1 Pa” displays; Ideal for professionals needing consistent precision
- Large LCD Display with Backlight and Fast Refresh: designed with a large backlit LCD screen, the gauge provides real-time digital readings with a 0.5-second refresh rate, making the evacuation process visible at a glance—even in low-light environments; The backlight turns off automatically after 20 seconds to preserve battery life, while the auto shutdown kicks in after 10 minutes of inactivity
- Hvac-compatible Design with Durable Build: comes with a universal 1/4'' SAE Flare (7/16-20 UNF) connection and supports multiple departments: mBar, mmHg, μmHg; The gauge can withstand up to 14 PSI (0.1 MPa) and operates efficiently from 0–50°C (32–122°F); It's an excellent tool for HVAC technicians, refrigeration maintenance professionals, and vacuum system monitoring; Note: only suitable for atmospheric environments—avoid refrigerants or reactive gas
