Product Registration Martel Calibrators – Fill out this brief form to register your new Martel BETA Calibrator. Martel Electronics offers quick and economical re-calibration so your calibrator will always be up to factory precision standards (NIST-traceable of course). In addition, by registering you’ll receive notifications of available firmware or hardware upgrades. For best possible performance, your Martel BETA calibrator should be re-calibrated at least once a year, depending on your quality system requirements. If you would like to see a sample calibration certificate, check out the Download Center. We offer up front pricing on our RMA Form as well so there is no guess work involved.
