Where it Began

It started in 1946 with an enterprising idea. There were leaks in the roofs and plaster walls of buildings in New York City. Building superintendents needed a way to identify them for repair. Enter Bill Delmhorst and his proprietary moisture meter. He sold it to the city, and Delmhorst Instrument Co. was born.
