Polycontrols has emerged over the years as an authority in understanding thermal mass flow technology. We have mastered and set higher standards for the calibration of gas flow meters and controllers.
We are also the reference for the calibration of gas meters, having developed a unique
procedure for the calibration of diaphragm and rotary meters.
Our standard calibration gases include Dry Air (D.P. -40C), Nitrogen, Argon, CO2, He and Hydrogen. We can calibrate all major brands and most gas flow technologies including thermal mass, laminar, Coriolis, sonic, turbine, variable area, orifice plate and much more.
