Digital Micron Vacuum Gauge 0-750k Microns HVAC Pressure Gauge 1/4 SAE Male Fit

Monitoring Mode & Buzz Alarm：Our Digital Vacuum Gauge HVAC Divided into normal and monitoring mode, Under the monitoring mode, If the current pressure is lower than the designated pressure at this time, an alarm will run. When current pressure is higher than the set pressure, the alarming will automatically disappear, or pressing any key, or automatically disappear after 30 seconds. The monitoring mode allows you to control the vacuum pressure more easily. 13 Types Meassurement Units：Our Micron Gauge HVAC have a total of 13 conversion units (mmHg, inHg, umHg, ftH2O, cmH2O, inH2O, Pa, Kpa, mbar, bar, Kg/cm, psi, oz/in). You can convert the units according to your working requirements to cope with complex working problems. High Precision：Our digital vacuum gauges can detect even finer changes in vacuum pressure. Measurement range is 0-750,000 microns/ 0-999 mbar, Smaller range means more accurate detection. Minimum Resolution: 1 micron (0-1,000 microns); Measurement Accuracy: +/- 10% (100-1,000 microns).
