Clarostat is the leading manufacturer of panel-mount potentiometers in the United States. Clarostat also makes other test equipment, such as decade resistors, custom optical switch solutions, and photoelectric solutions for commercial and industrial applications. Clarostat was the pioneering company of thick-film, wire-wound conductive plastic pots. Honeywell International, Inc., a Fortune 100 company, acquired Clarostat several years ago. The Clarostat brand name is still on Honeywell products such as potentiometers, resistors, encoders, trimmers, panel controls, rheostats, and optical switches. You will find used and refurbished Clarostat products at ValueTronics.com. The original manufacturer no longer carries many of the refurbished products on our site.
