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

The Signet 2610 optical sensor cap is calibrated at the factory and requires no field calibration. The optical measurement technology resists abrasion and bleaching allowing for a long life in many harsh applications. The DO sensor has a built in Modbus RS485 and 4 to 20 mA current loop outputs for ease of interface to existing control systems. Additional features include a 32.8ft (10m) cable with stripped and tinned ends as well as a titanium thermistor for improved compatibility in salt water applications.

Applications include:

• Municipal and Industrial Wastewater Treatment
• Drinking Water Reservoir Monitoring
• Environmental Water Discharge Monitoring
• Aquatic Life Support
