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.

Brief description The high-quality materials and components of the JUMO tecLine HD electrodes make them particularly suitable for the most demanding applications in process and industrial measurement technology. They are combined combination electrodes (with a reference electrode and a glass or metal electrode in a shaft).Depending on the design, it is possible to integrate an additional Pt1000 temperature sensor.Insensitive to large amounts of dirt as well as processes and waste water rich in oil and grease. For processes with a high solids content (e.g. waste water with sand particles or media that are subject to precipitation or crystallisation reactions), a perforated diaphragm variant is available as the optimum solution. JUMO tecLine HD electrodes represent the latest technology for pH and redox electrodes. Each electrode is a high-quality product that is individually unit-tested and comes with a calibration certificate. Modern production facilities guarantee constant values.All conventional electrodes are made from physiologically safe and FDA-listed materials.Their shaft glass is lead-free and therefore RoHS 2 compliant.
