Martin Calibration Services Enters Exclusive Partnership with National Association for Proficiency Testing

The National Association for Proficiency Testing (NAPT) is thrilled to announce an exclusive partnership with Martin Calibration Services.

Eagan, MN, April 24, 2024 - The National Association for Proficiency Testing (NAPT), the most trusted name in the metrology community for providing administration, development,  software tools, and support for interlaboratory comparisons, is thrilled to announce the inclusion of Martin Calibration Services, a premier provider of both on-site and in-lab calibration for the aerospace, automotive, medical, nuclear and manufacturing sectors, to our list of exclusive partners. 

Under this agreement, Martin Calibration has chosen NAPT as the sole partner for its proficiency testing requirements. For over twenty-five years, Martin Calibration has relied on NAPT not only for proficiency testing kits but also for collaborative efforts aimed at enhancing NAPT's suite of services for the metrology community.

Martin Calibration has selected NAPT as its exclusive PT Provider, demonstrating a strong endorsement of NAPT's commitment to excellence. In addition to enrolling in NAPT-sponsored ICL/PTs, Martin Calibration will now be able to manage its quality program and accreditation requirements in-house with the help of additional metrology tools offered by NAPT, which include the NAPT Intra Wizard and the QMS Accreditation Manager.

Corey Garbers, President of Martin Calibration, emphasized the unparalleled value NAPT offers. "When you compare what NAPT offers to what the other PT providers offer, there is no comparison," said Mr. Garbers. "First and foremost, NAPT is the only proficiency testing provider we trust with our proficiency testing requirements. Several factors set them apart from other providers: the largest number of available kits to the online customer portal, the fantastic customer service, and the additional software that allows us to manage our own internal program. In short, there is no comparison."

Richard Brynteson, Managing Director of NAPT, expressed his excitement about the expanded partnership: "This exclusive agreement with Martin Calibration Services is a testament to the strength of our collaboration and the value we provide to our partners. We are thrilled to continue working closely with Martin Calibration to deliver exceptional proficiency testing services and support to the metrology community."
