OVERVIEW
With advanced microprocessor technology and state-of-the-art silicon pressure sensors, the 672 series precision
pressure calibrators provide a pressure calibration solution for gauges, transmitters, and switches over a wide
pressure range. The 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 40,000 psi (2,800 bar), every silicon pressure sensor in our gauges has been
specially aged, tested and screened before assembly. The 672 series precision pressure calibrators are unmatched
in performance and reliability.
