How often should pressure gauges used on test equipment be calibrated?

Calibration of pressure gauges used on test equipment is critical for ensuring accuracy and reliability. It is recommended that these gauges be calibrated semiannually. This frequency helps maintain the precision required in measurements, especially in environments where safety is a priority, such as those involving fire extinguishers and other safety equipment.

By calibrating the gauges every six months, users can catch any drift in readings that may occur over time due to wear, temperature changes, or other environmental factors. This routine maintenance minimizes the risk of relying on inaccurate data, which could lead to improper assessments of extinguishing agents or fuel supply levels.

Maintaining a semiannual calibration schedule strikes a balance between ensuring operational reliability and avoiding excessive downtime or unnecessary costs associated with more frequent calibrations.
