About JM Test Systems, Inc.

Our commitment to accuracy, reliability, quality and service is what will make JM Test Systems stand out for you. We are an ISO/IEC 17025 lab accredited by A2LA, providing NIST Traceable calibration and repair for your test equipment. JM Test Systems complies with ANSI/NCSL Z-540 and ISO 10012-1. Whether you are looking for new or used equipment, you’ll find it all here.

Our founder, Ed Morrison, was an equipment manager for a large Instrumentation and Electrical contractor in Louisiana. While working there, he saw the importance of delivering quality, certified, test equipment to a jobsite and the importance of that test equipment to the success or failure of the job. This meant finding quality vendors to clean, service and verify the calibration of the equipment after every job was over. After years of fixing the equipment himself or struggling to find vendors who could live up to his standards, Ed decided to start JM Test Systems.

Today, we are still a family owned business with the same core values we started with. Our goal is very simple, to make all aspects of acquiring and managing test equipment easier and more efficient for you. From construction through project completion to turnarounds, we have every test equipment product or service you need to be successful. We understand that it is much easier to call one source for all of your test equipment & safety needs than to search multiple vendors for each product and service.

We’re the experts when it comes to test equipment and testing… it’s all we do, and we’ve been doing it successfully for 30 years. We’re here 24 hours a day, 365 days a year.
