Dwyer Instrumentation

For many years, Dwyer Instruments has been known and appreciated as a trusted leader in the measurement and control sectors. The company has made a name for itself by manufacturing innovative instrumentation solutions for the worldwide HVAC and process automation markets. Dwyer is first and foremost an instrument company. When we need to take a measurement, be it flow, pressure, or temperature, we look to Dwyer’s products as the types of devices that serve the basic function of a measurement instrument.

The company’s instrumentation lineup spans air velocity instrumentation, pressure gauges, rugged transmitters designed for tough environments, and a few other types of measuring devices. Dwyer is a unique company in a couple of ways: It covers a breadth of technologies which delivers advanced temperature and process controllers, and proximity controls built for demanding automation tasks. In a world where even the best instruments sometimes need constant "tuning" or recalibrating to be truly reliable, Dwyer has carved out a nice niche for itself by delivering straightforward instruments that give straightforward results.
