TM Electronics, Inc. was established in 1961 as a manufacturer of measuring instruments for the metal fabrication industry.

The company was purchased in 1981 and the business was re-characterized to focus originally on the measuring needs of the medical device industry. In the following years, product lines were developed to provide measuring equipment for improving quality and productivity in the automotive, electronics, industrial, pharmaceutical and food manufacturing markets as well as medical device manufacturers.

The test instruments focus on proving the liquid or gaseous integrity of the product to prove the product's integrity. A related product line is sold for testing porous and non-porous packaging of medical devices, certain types of food and pharmaceuticals for seal strength or package leakage. More recent product developments include a line of non-destructive test systems for flexible, non-porous closed products or packages.

TM Electronics is now part of Industrial Physics LLC.
