Hydraulic pressure gauge is a common tool for measuring pressure, widely used in aviation, machinery, automobile and other industries. Due to frequent use, the accuracy and reliability of hydraulic pressure gauges also decrease, so they need to be inspected and replaced regularly. Generally speaking, the validity period of hydraulic pressure gauges is one year, and they need to be replaced after the validity period.
The service life of hydraulic pressure gauges is affected by many factors, such as the use environment, maintenance, frequency of use, etc. Generally speaking, the service life of hydraulic pressure gauges is between 2-5 years. Therefore, in order to ensure the accuracy and reliability of hydraulic pressure gauges, they need to be inspected and calibrated once a year.
