Pressure Calibrator for Pressure Transmitter Calibration

The ADT 672 series of pressure calibrators are precision digital pressure gauges with electrical measurement for pressure transmitter calibration. The ADT-672 is a very portable device and can measure pressure precisely with a built-in pressure sensor, as well as read the current or mV produced by a transducer. It can even supply an excitation voltage to power sensors or transmitters during calibration. In order to reach 0.025% F. S. accuracy up to 10,000 psi (700 bar) and 0.1% F. S. accuracy up to 36,000 psi (2,500 bar), every silicon pressure sensor has been specially aged, tested and screened before assembly.
