YOKOGAWA DO70G Optical Dissolved Oxygen Sensor |
YOKOGAWA DO70G Optical Dissolved Oxygen Sensor
DO70G optical dissolved oxygen sensor is designed for using in water treatment plants such as sewage treatment works and effluent activated sludge process.
This optical sensor has a fast response time and good long term stability, and features replaceable sensor cap and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO70G sensor can be used in either the PB350G/PB360G floating ball holder or in the DOX8HS submersion type holder.
