Vacuum gauge calibration method

Today, vacuum is widely used in the production and manufacture of high-end products in our daily lives and plays an important role. For example: in research, industrial processes, mobile phone chips, hard drives, solar cells, plastic drying or food vacuum packaging .

In today's production activities, our requirements for the accuracy, standardization, reliability and repeatability of vacuum measurement are critical. When we are measuring, high precision is the key to the key:

The accuracy will directly affect the production quality of the product, the accuracy of scientific experiments and the reliability of equipment use.

Before performing the calibration, the following conditions must be met:

1. The system limit pressure ρE must exceed 50 times the minimum calibration pressure ρmin (ρE ≤ ρmin/50)

2. Ambient temperature must be constant (± 1 °C)

3. The calibration system must be thermally stable

4. Standard vacuum gauges and other vacuum gauges must be stable when measuring

To ensure high reliability when using the vacuum gauge, it must be calibrated or calibrated frequently. These calibrations must be in accordance with national or relevant international standards, depending on the specific requirements of each application.

In production activities, vacuum gauges often require calibration and calibration by external professional organizations. However, the use of economical measuring instruments for on-site calibration can save time and money in the case of large quantities or short calibration intervals.
