Do I need to calibrate the testers? If yes, how often?

The units are calibrated at the factory before delivery to your facilities, the report can be found inside the mesh pocket og the carrying case. 

We suggest calibrating the testers at least once a year or as per local PUC or company regulations to ensure that your measuring instruments always perform according to expected specifications and standards. Calibration can be performed in house using a calibration kit and a NIST traceable standard.

If you would like to verify if your standard is compatible, please contact us at support@probewell.com.

We also offer calibration services at our lab, please send us an email to info@probewell.com for an RMA estimate and return instructions.
