Hard Gage Calibration

Hard gage calibration requires state of the art equipment to ensure the highest degree of measurement uncertainty.

With this equipment, and our custom-designed software, we are able to offer you the best possible turnaround time, and pricing in the industry.

The hard gage calibration lab is held at 68°F with relative humidity not to exceed 45%. Both temperature and humidity are closely monitored by our Honeywell environmental control unit.

We also have a suspended floor to help avoid unnecessary vibration and ensure a good measurement uncertainty of all of our equipment.
