Customer Testimonials



JM Test Systems has greatly simplified the maintenance of our test equipment by bringing their calibration trailers onsite. What used to take months to get all of our equipment calibrated by sending a few items out at a time is now accomplished in days with no test equipment being unavailable for more than a few hours.

Mike Kelsheimer | Marathon Petroleum Co.

I would recommend JM to other companies that use calibration services because they come to our office location to calibrate and test our instruments. It is much more convenient for our field employees with very little down time to use their prompt services.

Richard Horton | Oneok Field Services
