• Wide Measurement Range: This digital vacuum gage features a high sensitivity sensor that provides accurate readings from 75000 μmHg (atmospheric pressure) to 0 μmHg, with an accuracy of ±10 μmHg or ±10%. It's the choice for leakage detection in HVAC and refrigeration systems, ensuring reliable performance even in accuracy tasks with a resolution of 1 μmHg below 30000 μmHg.
• Smart App Reminds and Offline Recording: Stay in control even when you're away! Connect to the app for real time reminds, data monitoring, and offline recording. With built in temperature compensation, your vacuum readings will remain accurate under varying environmental conditions.
• Dual Calibration Mode: Experience lasting accuracy with support for full scale and 0 point calibration. Easily calibrate in atmospheric conditions or using a vacuum system, ensuring consistent accuracy for workers who demand reliability in their measurements.
• Large LCD Display with Backlit and Fast Refresh Rate: The large backlit LCD screen refreshes every 0.5 seconds, providing clear and immediate digital readings during the evacuation process, even in low light environments. The backlight automatically turns off after 20 seconds to extend battery life, and an auto shut off feature activates after 10 minutes of inactivity.
• HVAC Compatible Design and Durability: Engineered with a universal 1/4 inch SAE (7/16-20UNF) connection, this vacuum gage operates efficiently under pressures up to 14 PSI (0.1 MPa) and within a wide temperature range of 0-50℃ (32-122℉), making it an essential tool for HVAC technicians, refrigeration maintenance professionals, and vacuum system monitoring.
