Saysurey Digital Vacuum Gauge, 0-75000 μm Hg HVAC Vacuum

Saysurey Digital Vacuum Gauge, 0-75000 μm Hg HVAC Vacuum Pressure Meter with 7/16"-20UNF, HVAC Digital Vacuometro Tester Set with Buzzer Alarm, 1/4" SAE Extension Connector Fitting,Brass Adapter
- 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
