Industrial Scientific Corporation is an American company headquartered in Pittsburgh, Pennsylvania that designs and manufactures gas detection products that protect workers from hazardous conditions around the world. Key markets include utilities, chemical production, oil and gas, steel and coke, paper industry, fire service, construction, military, insurance companies, food service, and general industry.

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.

In 1985, NMS sold the division to founder Kenton McElhattan, and Industrial Scientific started its operations as a private company. The catalyst for the separation stemmed from an argument with NMS's Scottish majority owner over a used microscope worth $600.

In 2015, Industrial Scientific moved into a new 200,000 square foot headquarters in Robinson Township, Pennsylvania, consolidating their operations from four buildings in Oakdale, Pennsylvania and Findlay Township, Pennsylvania into one.

In 2017, Industrial Scientific was acquired by Fortive, the parent company of Fluke, Tektronix, among others.
