Mid-West Instrument

Mid-West® Instrument was founded based on innovation back in 1958.

At that time a customer approached Mid-West® Instrument with the need for monitoring pressure drop across a filter. The founders, a group of engineers, developed the model 120 differential pressure gauge. It was then a heritage of working with customers to solve their application needs was born. A second customer approached Mid-West® Instrument with the need for a leak detection gauge, the founders again developed a solution with the model 109 which was based on differential pressure. At this point Mid-West Instrument set out to find more customers with applications that required solutions.
