We can adjust most pressure gauges that are not permanently sealed to correct small errors or minor overpressure effects.

If a gauge has experienced excessive overpressure, it may require replacement instead of adjustment.

Yes, but if the fluid has leaked out of the gauge, the leak must be repaired first.

Often, yes. We can replace many lenses unless the instrument case is permanently sealed by welding or brazing.

We apply a $26 high-accuracy fee to pressure gauges that require certification at better than 1.0% accuracy.

For gauges rated at 1.0%, 2.5%, or higher, we test at 5 measurement points. When a gauge requires accuracy below 1.0%, we increase testing to 10 measurement points, which requires additional time and higher-precision reference equipment.

We apply a $100 ultra-high accuracy fee to pressure gauges that require certification at better than 0.1% accuracy.

For these calibrations, we test at 10 measurement points and typically use primary standards, such as piston gauges. The fee reflects the additional time, precision, and equipment required to calibrate high-accuracy pressure instruments, including transducers and calibrators.

We perform the final test point at half of the gauge’s range as part of a hysteresis test. This verifies that the gauge remains repeatable after being pressurized.

Some customers see this final reading and assume it represents the highest measurement. However, when you review the full certificate, you’ll find the higher measurement points listed earlier in the test data.
