As a measuring instrument, pressure gauges are mainly used for safety protection, industrial process control, monitoring and monitoring of pressure. The accuracy of the pressure gauge display is crucial for the operation of equipment and facilities, therefore it is necessary to regularly inspect the pressure gauge.

At present, the general practice of enterprises is to conduct an annual inspection of all pressure gauges, and some enterprises with strong economic strength undergo a semi-annual inspection. Some safety supervision and law enforcement personnel also hold the view that "all pressure gauges must be inspected every year or six months", and order enterprises to rectify pressure gauges that have not been regularly inspected within a specified period of time.

So, do all pressure gauges require mandatory periodic calibration? What is the calibration cycle? How to handle the issue of "pressure gauges not regularly calibrated"? From the perspective of safety production law enforcement and supervision, this article explores the issues related to pressure gauge calibration based on laws, regulations, rules, and normative documents, in order to find a strong law enforcement basis for safety supervision law enforcement and avoid unnecessary administrative reconsideration and litigation.
