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

I have found everyone at JM Test to be very professional and very helpful on any questions I have. We are also very pleased with their onsite services.

Larry Burford | Continental Structural Plastics

Their service is great! Them come to us and test all of our equipment on site. Their service is fast and professional. I would recommend the services we have used to anyone.

Matt Sorenson | Northeast Nebraska Public Power District

Very knowledgeable about my needs for onsite calibration test and repairs. Information is logged into the system. This make things simpler for me.

Brad Frederick | Birla Carbon (Columbian Chemicals)

I have used JM Test with a few different companies. They were always the same – nice and helpful. JM Test has always helped me with any needs I have had with test equipment.

Jason Winston | Powell

What I like about JM test Systems is the fact that they come to us to test our equipment, they have a professional staff performing the testing and all of our certification paperwork is organized and placed binders for easy access.
