Gauge Calibration and Repair Services

When your gauges are due for calibration, send them to Kent Machine.

We will inspect your gauge and,

If it is found to be in tolerance, it will be returned to you with an ISO 17025 report.

If the gauge is found to be out of tolerance, you will be informed of the gauge’s condition and, if it is repairable, you can request a quote for repair or a quote for a new gauge.

Our in house manufacturing and heat treating capabilities allow us to react quickly and get your gauge back to you in a timely manner, minimizing any disruption to your manufacturing operations.

For additional information or for your personal consultation regarding your component or product please select the “RFI” request information selection button to begin your communication.
