Since their 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.
