The ADT 672 Digital Differential Pressure Calibrator with HART provides pressure calibration solutions for gauges, transmitters and switches with a wide selection of pressure ranges. The ADT 672 precisely measures pressure with a built in pressure sensor, reads the current or mV produced by the transducer and provides 24 volt loop power to operate the device under test.
