The Georg Fischer / GF Signet 2610 Dissolved Oxygen Sensor is a rugged, reliable optical sensor designed to deliver accurate DO data across a wide measuring range while reducing maintenance costs. It features the latest optical technology and eliminates the need for membrane and reference solution replacement.

The factory-calibrated optical sensor cap requires no field calibration and provides a one-year measurement life. Optical measurement technology resists abrasion and bleaching, ensuring long life in harsh applications. A titanium thermistor improves compatibility in salt water applications.

The sensor includes built-in Modbus RS485 and 4-20 mA current loop outputs for easy interface to existing control systems. It supports salinity compensation from 0-42 PSU and barometric pressure compensation from 507-1115 mbar, both available as fixed or real-time values. With a maximum pressure rating of 300 psi and operating temperature range of 32-122°F, the 2610 is suitable for municipal wastewater treatment, drinking water reservoir monitoring, environmental discharge monitoring, and aquatic life support applications.
