Chlorine (HOCl, HOBr or ClO2 ) & Temperature
KAPTA 2000-AC2 In-line Chlorine Sensors General description
The KAPTA 2000-AC2 probe has been specifically developed to measure free chlorine (HOCl) and temperature directly within a pressurised pipe for many applications including management and control of a drinking water network, real-time, rapid control of chemical dosing for industrial water processes and cleaning regimes and management of chlorine levels within swimming pools and spas.
The KAPTA 2000-AC2 is an amperometric sensor using a structured photo-polymerised membrane directly on the electrode which suppresses the well-known drawbacks of amperometric sensors with electrolyte, such as pressure and flow sensitivity, and enables the probe to be installed directly within pipes up to 10 bar flow pressure without flow or pressure control.
The sensor principal also eliminates the need for field re-calibration and on-going routine membrane replacement allowing both long-term stability of the signal and reduced maintenance costs. The principal of the measurement is based on a Clark-type cell with a working, counter and reference electrode.
The sensor design includes a simple replaceable head which is easy to handle and requires no reagent or electrolyte. As the lifetime of the sensor can vary with the application, this design allows more flexibility and price improvement for critical applications.
