Model DO30G
Galvanic Cell Dissolved Oxygen Sensor
Product Information
The DO30G sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming and other fields where water quality is important.
This galvanic cell has a fast response time and good long term stability, and features replaceable diaphragm and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO30G sensor can be used in either the PB350G/PB360G floating ball holder or in the DOX8HS submersion type holder.

Featuers
| * | A DO sensor that uses a special electrolyte, shortening the electrolyte stabilization time and realizing stable measurements over a long period of time. |
| * | Measuring range of 0 to 20 mg/l. |
| * | A membrane that is easily replaceable by anyone because of the cartridge type. |
| * | A membrane 50 mm thick that is hard to tear and has reduced influence from air bubbles. |
