Product FAQ's

Ask a Question

  • Which pressure gauge should I purchase to use with my hand operated Pressure Calibration Pump?

    The Accu-Cal Plus Digital Gauge or the Accu-Cal Series 25554 Precision Test Gauge. When ordering, make sure you order the same pressure range as your sample gauge. Example: If you would like to calibrate a 250 ft. gauge, your test gauge should also be that same scale – 250 ft. If you any questions when ordering, please feel free to contact your Amron Sales Representative.
