Digital Vacuum Calibrator mainly used to validate and cross check for Vacuum generated in Vacuum Leak Tester . A further advantage is that digital pressure gauges can also be used as a pressure reference. This enables the easy testing, adjustment and calibration ( Auto Zero before every test) of other pressure measuring equipment directly on site. Through an efficient measuring sensor , a high accuracy of 0.05 % FS is achieved. Simple operation with 3 tactile switches and auto calibration is incorporated. Backlit allows the view screen ( 2 X 16 LCD) and easily different pressure units are configurable.
