Dissolved Oxygen Sensor

Possible measurement for waste water, drinking water, sea water and surface water (others upon request)

The measurement sensors from WaterSam can be connected directly to the MS3 controller, without requiring a transmitter or amplifier. This makes it possible to add them to any WaterSam sampler, whether stationary or portable. Multiple sensors can be operated simultaneously, and switching between sensors is quick and easy. It is even possible to utilize products from other manufacturers, if desired.

The oxygen probe utilizes optical measuring technology, and conforms to the ASTM International D888-05 norm for the measurement of oxygen. This technology does not consume oxygen, allowing a highly accurate measurement under all circumstances.

The intelligent sensor saves data such as calibration directly in the sensor. This enables “play-and-play” usage without requiring recalibration.

Transfer of data is accomplished by means of a Modbus protocol.

Advantages:

  • Calibration data stored directly in sensor
  • For highly diverse applications
  • Data transfer via Modbus RS-485
  • Robust housing made of stainless steel or titanium
  • For mobile or stationary applications
