Type 8232 – Chlorine sensor
The 8232 from Bürkert is an electrochemical sensor for measuring the free or total chlorine content of an inorganic source (chlorine gas, sodium hypochlorite solution, …). Four variants of Type 8232 are available:
- The “Trace” chlorine sensor (zero chlorine) equipped with three electrodes is suitable for measuring very low concentrations of free chlorine. The diaphragm of this sensor is protected against biofouling and can therefore work for up to four weeks in water without chlorine. It has a voltage output on a 5-pin M12 circular male connector.
- The free chlorine sensor with three electrodes offers greatly reduced pH dependency. The sensor has a current output on a 5-pin M12 circular male connector and is designed for applications in swimming pool, drinking or sea water. The liquid must contain a minimum chlorine concentration (≥ 0.1 ppm).
- The free chlorine sensor with two electrodes delivers a current output on a 5-pin M12 circular male connector. This sensor is designed for use with swimming pool, drinking or process water. The fluid being measured must not contain any cleaning agents (e.g. surfactants) or abrasive particles. The pH value must be kept at a constant level. The fluid must contain a minimum chlorine concentration (≥ 0.1 ppm).
- The total chlorine sensor with three electrodes offers greatly reduced pH dependency. The sensor has a current output on a 5-pin M12 circular male connector and is suitable for applications in swimming pools, drinking or sea water, and brine. It measures total chlorine = free chlorine + combined chlorine.

| Measured variable | Free chlorine |
| Application | For monitoring absence of chlorine in reverse osmosis systems1.) (ze-ro-chlorine) |
| Measuring principle | amperometric potentio-static 3-electrode system with electronic inside (completely galvanically isolated, digital internal data processing) |
| Electrolyte | EMST1 gel |
| Measuring range | 0.005…2 ppm |
| Zero point adjust-ment | Not necessary |
| Cross sensitivities/Interferences | • ClO2, O3 influence the signal strongly. • High concentrations of bound chlorine can increase the measured value. • Corrosion inhibitors, Stabilisers for water hardness can lead to measuring errors. • Reducing agents can lead to a loss in slope. |
| Temperature com-pensation | Automatic (integrated temperature sensor) Sudden temperature changes must be avoided. |
| Maintenance2.) Control of the meas-uring signal Change of the mem-brane cap Change of the elec-trolyte |
