Calibration involves computerized tools, which we verify are working properly before beginning calibration. These pressure modules can set a specific amount of pressure, and we test your gage using that standard to ensure its readings are correct.
During vacuum calibration, our certified technicians set a known standard to the tested pressure points and take readings from your gage. We look for deviations between the standard and your gage’s measurements to determine where any issues are occurring.
For many instruments, we test five points within the gage’s capacity, which are separated by 20% of the total capacity.
When we perform high-accuracy calibrations, we inspect 10 points that represent every 10% of the total capacity.
During vacuum calibration, our technicians may determine your pressure gage is out of tolerance. This issue can happen for various reasons, and some problems are repairable. Depending on your gage and the problem causing inaccurate measurements, replacement may be a more suitable option.
Testing various points of your gage lets us pinpoint where inaccurate readings stem from. Our findings can help your company discern the problem.
A pressure gage calibration can help you determine the cause of the problem, you can decide whether repair or replacement is a more fitting option.
At Garber, we perform vacuum calibration services for gages that handle as much as 25 Hg. As with our pressure calibration services, we provide vacuum calibration both on-site and at our facility.
During vacuum calibration, we use computerized pressure modules that can calculate negative pressure capacities. We set a known standard for each pressure point and then inspect and compare each pressure point with the test gage’s readings. This process identifies any deviations from the standard, allowing us to pinpoint where in the system the error occurred.
Each instrument typically receives a five-point vacuum calibration, and we compare the test instrument with the standard instrument at every 20% of capacity. We also perform more precise 10-point calibrations if needed, during which we compare the instruments at every 10% of capacity.
