DO70G Dissolved Oxygen Sensor
Brand: Yokogawa Electric CorporationDO70G 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.
Features- A Optical DO sensor that uses a phase measurement method and realizing stable measurements over a long period of time.
- Measuring range of 0 to 25 mg/l.
- A sensor cap that is easily replaceable by anyone.
