Houston Calibration and Metrology Lab

The Rothe Companies have been providing in house calibration services for more than 50 years. The Houston Calibration and Metrology Facility was established in 1999 to serve the government, military, aerospace and commercial industry and has grown to one of the most diverse labs in Southeast Texas. Rothe has over 10 years experience calibrating all of Johnson Space Center’s test equipment, including all of the flight equipment aboard the ISS.

Our laboratory Quality Management System has been registered to ISO 9001 since 2003. In 2010 we became accredited to ISO 17025 and ANSI/NSCSL Z540-1. In 2016 we became accredited to ANSI/NCSL Z540.3 making Rothe one of the few labs in the Houston area to achieve this accreditation.

Rothe is able to offer superior service through the hiring of technicians trained in calibration by the US Military (PMEL) or those who have obtained the Certified Calibration Technician certification by the American Society for Quality (ASQ).

We offer on-site calibration services in the greater Houston area as well as other locations upon request. We can set up in your facility or use our mobile lab set up at your location.
