Gas pressure reducer calibrator
Mainly used for measurement and verification of gas pressure reducer pressure gauges such as oxygen, nitrogen, argon, helium, hydrogen, carbon dioxide, acetylene, liquefied petroleum gas, etc. As well as the detection of safety parameters such as leakage of gas pressure reducers.

.Traditional calibration method< br/> Overall calibration method
The pressure gauge being tested may be contaminated (for example, the water medium pressure pump is contaminated or the oil-water isolator no longer serves the isolation function), and installing it on a pressure reducer may cause safety hazards.
The work table is a gas medium, and the calibration medium is also a gas. It is scientific (not aroused enough awareness by people) and will not pollute the meter being tested.
The calibration medium of the pressure gauge is water, which may cause corrosion and reduce the risk of corrosion. The adjustment mechanism of the pressure gauge may malfunction, causing the adjustment mechanism to malfunction.
The verification medium is gas and does not contain any liquid medium and will never corrode the meter being tested.
The pressure gauge may be damaged after being reinstalled. It cannot be sealed and leaks (because it is impossible to measure, you can only feel it by hand).
The meter being inspected has not been disassembled in any way, and the original sealing of the gas pressure reducer has not been damaged.
.The pressure gauge after reinstallation , it is possible that the angle of view changes due to the failure to return to the original position, which brings inconvenience to use.
The meter under inspection has not been disassembled in any way, and there is no change in the angle of view of the pressure gauge on the gas pressure reducer.
Only. Calibrating two pressure gauges did not correctly determine the quality of the gas pressure reducer itself.
Not only were the two pressure gauges calibrated, but the quality of the pressure reducer itself was also verified.
. If a pressure reducer is specially designed for hazardous gases and its regulating mechanism has not been calibrated, it will easily cause an accident once the regulating mechanism fails or leaks and enters the production site.
The quality of the pressure reducer itself has been verified, and there will be no safety hazards. Enter the work site.
If it is not a special pressure reducer for dangerous gases, its adjustment mechanism is not tightly sealed. Since the surface cannot be found and cannot be eliminated, the gas source gas will leak slowly during work, resulting in a waste of gas source.
The quality of the pressure reducer itself has been verified and no waste will occur.
.If the low-pressure end pressure gauge is also calibrated with water medium (often two pressure gauges are calibrated with water at the same time), it will not be stipulated in Article . That is, for pressure gauges with an upper limit of measurement not greater than, the working medium is gas.
Both pressure gauges are calibrated using gas and fully meet the requirements of calibration regulations.
.
The calibration status is the working status of the pressure gauge, which is very scientific. This has been ignored by most certifiers.
The threads of the two pressure gauges on the manufactured pressure reducer are generally of the same size, while the threads of the pressure gauges on the imported pressure reducer have several sizes. During calibration, joints are required to transition, which makes the calibration work very cumbersome and inefficient.
