At Gurley Precision Instruments, measurement is our business. GPI was one of the first companies to develop the chrome-on-glass process necessary to manufacture optical encoder discs, and has since been a significant provider of optical encoders, optographic products and related devices. This tradition and commitment to measuring excellence is still very much alive today - as we offer as many standard and custom encoder options as any company in the business. Incremental, absolute and Gurley's own Virtual Absolute technologies in enclosed and modular rotary and linear configurations - each is available in prototype and OEM quantities.
Gurley is an ISO 9001 certified company.
