Fire Testing Instruments by Deatak
Our Evolution

The Govmark Organization, Inc. Instrument Division (the largest USA manufacturer of fire and flammability test instrumentation worldwide) has been producing high quality, reliable and robust test instruments at its NY facility since 1972. In 2008, Govmark Ltd was formed in McHenry Illinois to manufacture some of the Govmark test instruments under The Govmark Organization, Inc. brand.

In 2012, Govmark's instrument division was transitioned to Govmark Ltd to manufacture all the instruments formerly offered by The Govmark Organization, Inc. In 2015, Govmark Ltd changed its name to Deatak. Now an independent company, Deatak continues to meet industry demands worldwide as the USA's largest manufacturer of fire and flammability test instrumentation , producing the same great quality you've come to expect from the Govmark brand.
