Gauge Calibration and Certification

While modern pressure gauges are remarkably robust, even the sturdiest gauges experience wear and tear and accuracy degradation over time. Conditions such as vibration, pressure spikes, and mechanical shock can impact the accuracy of the gauge.

NFPA 25 mandates that test gauges be calibrated a minimum of annually, to an accuracy level of +/- 1 percent. Our service verifies, repairs and, if needed, restores the accuracy of a gauge to proper working conditions. (NFPA 25:
