Oxygen Sensor (Submersible Sensor OxyGuard using the galvanic principle)

The remarkable features of this oxygen sensor are its extremely long service life and the low maintenance costs due to its long-term adjustment and cleaning intervals.

The adjustment can be done in air or in saturated water without any calibration tables. The replacement of the galvanic cell is simplified by the design of the sensor. The membrane is very durable and is almost unbreak-able (100 µm membrane thickness).

Newly developed sensor electronics enable the oxygen sensor to work without an additional storage battery. The sensor can be modified to customer's needs regarding measuring range and accuracy.
The response time is less than 2 minutes.

The sensor can be immersed directly in water courses or tanks and does not need regular maintenance. The sensor is also available in combination with a temperature sensor.
