About Us
JMS Southeast was founded in 1980. Throughout its years of operation, it has secured a strong customer base from OEM and industrial customers whose production depends on quality and consistency in their temperature measurement.

We design and manufacture a complete line of high quality standard and custom temperature sensors including thermocouples, RTD's and thermowells as well as a wide selection of temperature accessories.

What sets JMS apart from the average temperature sensor manufacturer are the "extras" it provides to ensure customer satisfaction. The 24 hour Swifty Sensor Service (at no extra charge), our new calibration program that complies with ISO 9000 / OSHA PM 1910 and is NIST traceable, and the Rolling Purchase Order Program for special volume and OEM discounts are just a few of the "extras" that make us the best.

Throughout the manufacturing process, JMS includes quality inspections. Our Quality Control Department conducts the final quality inspection on 100% of all sensors. We ensure strict compliance with customer required specifications which may include those of ASTM, ASME, NIST, ANSI IEC, and ISA among others. We are ISO 9001 certified through Underwriters Laboratories Inc. File #A6759, so all our operation procedures and work instructions are in compliance with the ISO 9001 standard.

We take pride in offering excellent customer service and the highest quality products in the industry.
