Main highlights

PARAMETERS: Maximum overload pressure of vacuum gauge: 72 psi/0.5 Mpa; Accuracy: 0.1-1000 Pa (digital plus or minus 5%); Resolution: 0.01(＜10 Pa); Operating temperature: -23-122 ℉; Connection:7/16"-20 UNF(1/4" SAE). 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: The micron vacuum gauge defaults to the normal mode after it is turned on. Press "SET" button to active target vacuum set montioring mode. After target vacuum is set, press 'SAVE CAL’ to save and active monito mode, buzzer beeps periodic. When vacuum pressure reached set pressure,alert will be activated (screeflicker,buzzer beeps), press any key to quit alert or wait 35 seconds,alewill stop automatically.

HVAC DIGITAL VACUUM GAUGE: Digital vacuum gauge can measure the real-time pressure during vacuuming of the refrigeration system, suitable for dynamic monitoring of vacuum pressure changes in HVAC and heat pump systems. It can be used in conjunction with a vacuum pump to measure the real-time pressure during vacuuming, quickly and accurately judge the degree of dehumidification and impurity removal, and detection the vacuum system and refrigeration systemin real time.
