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.

Since then, Delmhorst has built a reputation for designing, manufacturing and marketing the highest quality moisture meters available on the market for a variety of industries. Every Delmhorst product is assembled in the USA, and is supported by our industry-leading warranty. Our commitment to product excellence and superior service began as a mission. Now, it is our hallmark.

Our meters provide consistent, accurate readings about the moisture level of your product. Whether you choose pin-type, or pin-free, the meters provide valuable information you need to make critical decisions.
