Determining the calibration cycle of pressure gauges requires comprehensive consideration of various factors. For pressure gauges used in critical equipment or high-risk processes, since the accuracy of their measurements is crucial for equipment safety and product quality, the calibration cycle is usually short, which may be a few months or even shorter. In some occasions where the accuracy requirement for pressure measurement is relatively low and the usage environment is relatively stable, the calibration cycle can be appropriately extended, such as one year or longer. At the same time, the type, manufacturing quality and previous calibration history of the pressure gauge also need to be considered. If a certain type of pressure gauge often has large deviations in previous calibrations or its manufacturing process is relatively weak, its calibration cycle should be shortened to ensure that it can always provide reliable pressure measurement data.
