MS02 Chlorine or Chlorine Dioxide Sensor Cube

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

The device is selectable to measure chlorine or chlorine dioxide in water. It is used within the Online Analysis System Type 8905 by being plugged into a spare fluidic backplane slot. 

The sensor cube contains a high precision membrane covered amperiometric sensor, based on microelectromechanical systems technology (MEMS). The measurement signal shows the Cl₂ or ClO₂ content within the sample water. 

The chlorine measurement reflects either the available chlorine HOCl or, if coupled with a MS01 pH sensor cube for pH compensation, the free chlorine. The electrical and fluidic connections are made via the connection panel of the system. 

The sensor cube is communicating via buS, so the recognition at the Online Analysis System is fully automatic. When plugging into a system you will find the sensor in the list of buS members for further customized adjustments.
