How Long Is The Pressure Gauge Test Valid?

The validity of the pressure gauge is usually one year. Pressure gauge is an instrument used to measure pressure, which is widely used in various fields, such as industry, medical treatment, scientific research and so on. Since the accuracy and reliability of the pressure gauge are essential for safe production and environmental protection, regular testing is required to ensure its normal operation. According to national regulations, the pressure gauge needs to be tested once a year. During the testing process, the accuracy, sensitivity and appearance of the pressure gauge will be checked, and the unqualified pressure gauge will be adjusted or replaced.
