Since our establishment in 1885, Cooper-Atkins has built a solid reputation as a leading manufacturer and provider of quality time, temperature and humidity instruments. The inventor of the first bimetal oven thermometer, David G. Cooper, founded The Cooper Oven Thermometer Company in 1885. During the 1960's, The Cooper Thermometer Company broadened its brand with the development of three cooking lines.

The acquisition of The Croydon Thermometer Company further expanded the consumer product line into weather instruments, and two separate marketing groups were established for the consumer and industrial markets to advance these new product lines. In 1984, the Industrial Division of (Electro-Therm) Electromedics was purchased, immediately launching Cooper into the Digital Thermometer business, and the company officially became Cooper Instrument Corporation strengthening its presence in the HVAC/R, OEM and Industrial markets. In 2001, the company became known as Cooper-Atkins Corporation after acquiring Atkins Technical, a leader in thermocouple instrument technology.

In 2003 and KTG, Inc., a developer of wireless enterprise solutions for temperature monitoring and food safety with hand-held PDA applications including inspections and training, and innovative software solutions was purchased and the company became known as Cooper-Atkins Corporation.
