For hygienic reasons, drinking water or other water that comes into contact with people often has to be treated with agents that kill microorganisms, often using chlorine. To ensure a high level of safety for the consumer, fully automated systems are used to monitor, control and document the concentration, with amperometric sensors providing a good monitoring option.
Our Neomeris Free Chlorine Sensors are specifically designed for disinfection applications in water treatment and swimming pools. There is a choice of four different ppm free chlorine measurement ranges. (Determination of free chlorine by amperometric method)Typical further applications are: Industrial waste waterCooling waterBottle rinsingIrrigation water in agricultureand many others.Signal outputThe measured value is easily and reliably transferred to your control or display system by means of a 4-20mA signal with a scaling of 0-2, 0-5, 0-10 or 0-20ppm.MaintenanceThe membrane cap mounted on the sensor, as well as the included electrolyte solution, are easily replaceable by the user. This regular maintenance on the sensor helps to extend the service life in the application and to always obtain an optimal measurement result. MountingThe sensor is mounted in the separately available flow cell and, in addition to this, we offer you the flow meter required for this to ensure stable measurement.Scope of delivery: 1 pcs.

These amperometric sensors with membrane are used to determine the concentration of free chlorine. They are able to measure various inorganic chlorine compounds, including chlorine gas (Cl₂), electrolytically generated chlorine, sodium hypochlorite (NaOCl), calcium hypochlorite (Ca(OCl)₂) and chlorinated lime (Ca(OCl)Cl). Testing for the complete absence of free chlorine is not possible with these sensors. Depending on the version, the sensors either supply a temperature-compensated current signal (4-20 mA) in an analogue version or a Modbus RTU signal via a digital interface. Calibration takes place in a downstream device such as an indicator, controller, recorder or programmable logic controller (PLC). The sensors can be connected directly to various transmitters or controllers. These supply the system with the required voltage and enable uncomplicated calibration. Areas of application: The sensors are used to measure free chlorine in drinking water, bathing water, industrial water, process water and cooling water.

The potentiostatic double gold electrode was developed to measure the free, inorganic chlorine and chlorine dioxide in water. It is used in the treatment of drinking water, bathing water and process water. A fixed potential is set between the measuring and counter electrodes, which are attached to the electrode body as a double-ring gold foil. A reference electrode is integrated as a cassette. An additional supply of salt in the reference electrode ensures a long service life. The measuring device connected to it determines the measuring parameter and the measuring range. The service life of an electrode depends on various operating conditions, such as the salt content (conductivity), the temperature and the degree of contamination. With drinking water quality and a normal ambient temperature (20 °C), the service life is generally 1 to 2 years. If the water temperature rises, the service life of the electrodes is significantly reduced. The electrode has an M12 connection. The thread is a PG 13.5 thread.
