Since the company was founded in 1931, customers have come to recognize Dwyer Instruments to stand for quality, reliability, and readily available low cost products. As a leading manufacturer in the controls and instrumentation industry, we continue to grow and serve major markets including, but not limited to HVAC, chemical, food, oil and gas, and pollution control. New applications are discovered daily through a cooperative effort between Dwyer and its customers. It has been these relationships with our customers that allow us to continue to develop market demand products and further our success from leading established brand names such as the Magnehelic® pressure gages, Photohelic® switch/gages, Rate Master® flowmeters, and Hi-Flow® valves. In addition to new product development, Dwyer has added to its success through several acquisitions and has achieved additional market recognition. Respected names such as Mercoid Controls, Love Controls, W.E. Anderson and Proximity Controls have created new markets and further build on the solid reputation that Dwyer has and continues to sustain.
