FAQ
What’s the Over pressure ?
Pressures up to the related pressure range, the digital pressure meter cannot display the measured value. If pressures up to the overpressure limit (200%FS), the accuracy in the data sheet could be affected. As a result, the inaccurate measuring instrument may not be recovered by calibration.
What is pressure gauge calibration??
Every measuring instrument is subject to ageing as a result of mechanical, chemical or thermal stress. As a result, over time, the instrument has become inaccurate. we provide calibration services, also, users can calibrate the instrument according to the calibration instructions we provide.
How often should calibration be performed?
To ensure they remain accurate, One year time periods being the most common interval of this approach. Generally, it is sufficient to avoid inaccurate measurement results before it goes out of tolerance. Certain scenarios require a shorter period and some scenarios require longer period.
