GPI’s three calibration laboratories are accredited to the ISO/IEC 17025:2017 standard. This accreditation was attained through a stringent assessment process performed by Perry Johnson Laboratory Accreditation INC. The accreditation demonstrates GPI’s technical competence for our defined scope and the operation of our laboratories quality management system.

GPI’s services in the scope of calibration is divided into 4 separate categories. These categories are best described by way of the example declared in our Scope of Accreditation through PJLA. They are as follows:

Hydraulic Torque Wrench – 50 lbf-ft to 20,000 lbf-ft
Pneumatic Torque Wrench – 50 lbf-ft to 20,000 lbf-ft
Hand Torque Wrench – 5 lbf-ft to 800 lbf-ft
Pressure Gauge – 20 PSI to 10,000 PSI

As “Your Partner in Reliability”, GPI strives to provide every customer with prompt, accurate and repeatable calibration service. We achieve this goal in part through our “state-of-the-art” computerized AKO calibration equipment, professionally trained calibration technicians, and finally, calibration procedures that are traceable to NIST.
