Digital Vacuum Gauge Vacuum Pressure Meter Gauge Tester LCD Display 0 to 75000 Micron 14 PSI App Monitoring Temperature Compensation for HVAC Refrigeration Systems

[HIGH ​ MEASUREMENT] Built with a high sensitivity sensor this digital vacuum gage delivers dependable readings from 75000 microns down to 0 microns. It offers fine 1 micron resolution below 30000 microns and accuracy of plus or minus 10 microns or 10 percent making leak detection and evacuation work more confident and efficient. [SMART MONITORING CONVENIENCE] Designed to keep you informed throughout service this vacuum tester supports app connection for real time reminders live data viewing and offline recording. Built in temperature compensation helps maintain stable measurement performance in changing jobsite conditions so your readings stay trustworthy. [CALIBRATION FOR CONSISTENT RESULTS] Support for full scale and zero point calibration helps this digital vacuum pressure meter maintain long term accuracy. You can calibrate in atmospheric conditions or with a vacuum system which gives technicians a practical way to confirm reliable performance before ​ HVAC or refrigeration work. [CLEAR LCD AND ] The large backlit LCD screen refreshes every 0.5 seconds so you can view fast clear readings during evacuation even in dim spaces. The backlight turns off automatically after 20 seconds to reduce battery drain and the auto shut off function activates after 10 minutes of inactivity. [BUILT FOR HVAC SERVICE] Equipped with a universal 1 4 inch SAE flare 7 16 20UNF connection this vacuum gage is ready for common HVAC and refrigeration tasks. It handles pressures up to 14 PSI and works in temperatures from 0 to 50 degrees Celsius making it a practical tool for technicians maintenance crews and system diagnostics.
