Additel ADT672 Digital Pressure Calibrators

Additel ADT672 differential pressure calibrator
With advanced microprocessor technology and state-of-the-art silicon sensors, Additel's ADT672 series precision pressure calibrators provide a pressure calibration solution for gauges, transmitters and switches in a wide pressure range. The ADT762 by Additel is a very portable device and cannot 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 excitatio voltage to power sensors or transmitters during calibration.


In order to reach 0.025%FS accuracy over ranges to 10,000 psi [700 bar] and 0.1%FS accuracy over a range to 36,000 psi [2,500 bar], every silicon pressure sensor in our gauges has been specially aged, tested and screened before assembly. Additel's 672 series precision pressure calibrators are unmatched in performance and reliability.
