Can a reference connector be made to my own specification?

Yes, we can revise the standard design to suit variations in your product.

How often do I need to calibrate my gauge?

There is no fixed time, calibration frequency is based on how often the gauge is used and the conditions that the gauge is exposed to. Frequent use and abrasive materials will require more frequent calibration, low use in a clean environment will allow less frequent calibration. Usually the user determines the calibration frequency.

If you need assistance selecting the correct gauge or have technical questions please contact us.
