This document is the user's manual for the Signet 2610 Process Optical Dissolved Oxygen Sensor. The sensor features the latest optical technology for DO measurement, and can deliver accurate dissolved oxygen (DO) data across a wide measuring range while reducing maintenance costs.
The Signet 2610 Process Optical Dissolved Oxygen Sensor is a rugged, reliable device designed to deliver accurate dissolved oxygen data across a wide measuring range. It features optical technology and comes with three standard outputs: Digital (S 3L), 4 to 20 mA, and ModBus RS485. The sensor body includes a removable nose cone, a 10-meter cable, an optical DO sensing cap, and a titanium temperature sensor.
