Industrial Scientific Corporation, headquartered in Pittsburgh, Pennsylvania, designs and manufactures gas detection products that protect workers from hazardous conditions around the world.

Industrial Scientific began in 1976 as the Research Division of the National Mine Service Company (NMS) with a focus on developing instrumentation to detect methane gas.

[1][2] In 1985, NMS sold the division to founder Kenton McElhattan, and Industrial Scientific started its operations as a private company.

[1] The catalyst for the separation stemmed from an argument with NMS's Scottish majority owner over a used microscope worth $600.

[6] In 2006, Industrial Scientific acquired Oldham S.A. of Arras, France, a company primarily manufacturing fixed gas monitoring Systems.
