Testo Calibration Services

Full Service for quality and security

Calibration of test and inspection equipment is essential to maintaining confidence and reliance on the readings obtained from them to operate your business. Whether motivated by regulatory requirements or by the need for assurance of measurements critical to a manufacturing process, regular calibration of your instrument is critical to having a reference based on known standards. Besides the full line of reference measuring instruments and the accredited calibration services that Testo offers, we also have a line of calibration equipment that you can use to perform your own calibrations. We cover temperature, humidity, air velocity, air flow, and differential pressure. You can view product information on our calibration instruments here.

The Testo Calibration Lab is accredited to ISO/IEC 17025:2017 and meets requirements of ANSI/NCSL Z540-1-1994 by Perry Johnson Laboratory Accreditation, Inc. (PJLA).  Our accreditation certificate and scope can be accessed by clicking on the link to the right.
