Digital Micron Vacuum Gauge - BELEY HVAC Vacuum Test Gauge with 13 Units Electronic High-Precision Negative Pressure Gauge of 7/16 -20UNF Interface 1/4 SAE
- ACCURATE MEASUREMENT: This digital vacuum gauge adopts professional high precision micron vacuum sensor, which has wide testing range and more accurate and fast. The measuring range is 99999~0.1Pa (740000~0.75Micron), and the accuracy is ±5% (at 20℃)..
- 13 MEASUREMENT UNITS : Our HVAC vacuum test gauges have more conversion units compared to other products. There are 13 conversion units in total (mmHg, inHg, umHg, ftH₂O,cmH₂O, inH₂O, Pa, Kpa, mbar, bar, Kg/c㎡,psi, oz/in²), you can convert the units according to your working requirements to cope with complex working problems..
- HUMANIZED DESIGN: The large HD screen has a backlight function, which allows you to work in dim light environment. The vacuum gauge has a built-in buzzer, which can be custom set to achieve a reminder alarm. At the same time the design of the rubber handle, it has a good sense of comfort, but also not easy to slip off. Automatic shut-off for 10 minutes of unoccupied use can help you save power..
- 4 CALIBRATION MODES: This Negative Pressure gauge in the normal mode, long press the "HOLD button" to enter the calibration mode. Then you can use the "DIF key" to switch the calibration mode, which are: atmospheric calibration, vacuum calibration, custom calibration, and restore....
