To maintain the accuracy of your tester, we recommend all Electrical Safety Testers get returned annually for calibration and inspection at our A2LA Accredited Calibration Lab.

We guarantee service for all instruments that are in production, as well as instruments discontinued for less than 5 years. Our ability to service discontinued instruments greater than 5 years is dependent upon parts availability.

We’ll calibrate your instrument within 5 business days of receiving it, or we’ll pay the freight. See your instrument’s journey first-hand.

Types of Calibration

Standard Calibration

Standard Calibration is our base calibration type and provides a certificate to state the instrument is calibrated using standards traceable to NIST. View Our Standard Calibration Certificate

ISO Calibration

Accredited Calibrations provide measurement data and uncertainty traceable to the National Institute of Standards and Technology (NIST). If an auditor will be visiting your facility, they will likely require an accredited calibration certificate that includes tractability to NIST. View Our ISO 17025 Accredited Calibration Certificate

Other Calibrations

Need ANSI Z540, Denan’s Law, or CTL Specification Accredited Calibrations?
We have partnered with a local calibration house to accommodate calibrations that we can no longer accept such as ANSI Z540, Denan’s Law, or CTL Specification Sheet DSH 251B Accredited Calibrations. If our calibration offerings no longer meet your needs, please reach out to:
