Cryoguard™ Corporation, a division of Controlled Chemicals Inc., was founded in 1984 in Ann Arbor, Michigan. 

Cryoguard Corporation manufactures thermal exposure indicators, called Cryoguard Thermal Exposure Indicators, for ensuring the quality of heat sensitive material. The indicators were developed by the corporation’s founder in response to a request from U.S. Navy scientists who needed a temperature sensor for assuring the quality of blood products being shipped to the battlefield.

Over the years, the indicators have proved useful for a broad range of medical, scientific, and commercial applications. The company is a leader in quality control for cryogenic materials.
