Digital Vacuum Gauge, Micron Vacuum Gauge Tester with 11 Units, 7/16 inch-20 UNF, HVAC 0-75000 Microns Rang, Including 1/4" SAE Fitting and T-Connector, Battery Not Included

ROGVOC Digital Vacuum Gauge, Micron Vacuum Gauge Tester with 11 Units, 7/16 inch-20 UNF, ±10% Accuracy, HVAC Pressure Tester for 0-75000 Microns Rang, including 1/4" SAE Fitting and T-Connector

• HVAC DIGITAL VACUUM GAUGE: Digital vacuum gauge can measure real-time pressure during refrigeration system evacuation and vacuuming. Ideal for dynamically monitoring vacuum changes in HVAC and heat pump systems. Used with a vacuum pump to assess dehumidification, impurity removal, and overall system integrity quickly and accurately
• PARAMETERS: Maximum overload pressure of vacuum gauge: 2bar, Accuracy: ±(10% reading + 10 μm)(100-1,000 μm), Resolution:1 um to 5000 um, Operating temperature: 14-122 ℉; Connection:1/4 SAE(7/16" - 20 UNF) external thread. Digital HVAC vacuum gauge uses pirani vacuum sensor, which can respond quickly and accurately measure micro-pressure changes in vacuum
• MONITORING MODE AND BUZZER PROMPTER: Built-in visual alerts and buzzer activate instantly when the preset target vacuum level is reached. This crucial feature helps technicians prevent over-evacuation and avoids wasted time, ensuring optimal efficiency during system servicing
• WIDE UNIT SUPPORT & BACKLIT DISPLAY: Features 11 selectable vacuum units: microns, mTorr, umHg, Torr, mmHg, Pa, hPa, kPa, mbar, psia, inHg. Vacuum gauge tester with a large backlit display for clear readings in all environments, including dark spaces
• PACKING INCLUDES: digital vacuum gauge x 1, portable tool bag x 1, 1/4" SAE Fitting x 1 , T - Connector x 1 and user manual. We provide 7 x 24 hours customer support. (Powered by 3 x AA batteries, not included.)
