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

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.
