About JM TEST SYSTEMS LLC

JM Test Systems, LLC was founded in 1982 to provide quality and expedient service to industries that need repair and traceable calibration of test and measurement equipment. The company has grown from a 2 person lab to our current status of over 500 plus employees, and 10 laboratories.

Our quality is second to none, we are A2LA accredited to ISO 17025. Along with our ISO 17025 accreditation, we comply with ANSI/NCSL Z-540-1 and ISO-10012. We are members of the professional groups: NCSL International, ASQ, and GIDEP.

Our corporate office is located in Baton Rouge, LA along with our Baton Rouge Calibration Laboratory. At this location we specialize in temperature, dimensional, electrical, electronic, gas detectors, moisture analyzers, torque, analytical, and pressure equipment. This facility also specializes in the repair and certification of process instrumentation.

In Baton Rouge we also have our electrical safety testing facility, which specializes in electrical personal protective equipment (PPE).

Our Alexandria, LA facility located within the England Air Park was once the U.S. Air Force England AFB calibration laboratory. It primarily services the communications industry, DoD contractors in aircraft and shipbuilding industries and serves as a general purpose calibration facility for North LA, NE TX, and AR.

Our location in Odessa, TX offers a complete metrology lab for repair, calibration and certification of pneumatic, hydraulic, and temperature instruments and services the West, TX area.

Our newest locations include North Dakota, Pennsylvania, Illinois, and Mississippi.

Beside our fixed location we also have mobile calibration labs that can go to the client’s location and perform calibrations and certifications, with the same precision as any of our fixed laboratories.

In recent years, we have expanded our services to include selling test equipment, as well as renting test equipment.

We also design and manufacture custom built test benches to your specifications and manufacture our own line of pressure generation equipment.
