ADT 672 series Digital Pressure Calibrators

With advanced microprocessor technology and state-of-the-art silicon pressure sensors, the ADT 672 series precision pressure calibrators provide a pressure calibration solution for gauges, transmitters, and switches in a wide pressure range. In a highly portable package, it can not only measure pressure precisely with a built-in pressure sensor, but can also read the current or mV produced by the transducer, and can even supply an excitation voltage to power sensors or transmitters during calibration. To reach 0.025% F. S. accuracy over ranges to 10,000 psi (700 bar) and 0.1% F. S. accuracy over range to 36,000 psi (2,500 bar), every silicon pressure sensor in gauges has been specially aged, tested and screened before assembly. ADT 672 series precision pressure calibrators are unmatched in performance and reliability.
