NOTE: Using the sensor without mounting it in the supplied flow cell will lead to incorrect
measurement results; it cannot simply be submerged in a pipe, basin, channel or tank.

If no chlorine is to be measured for over 24 hours the sensor must be disconnected from the
analyser, the membrane cap emptied, rinsed and the sensor stored per instructions.

filling the membrane cap with electrolyte.
The membranes can be damaged by high pressure  The sensors should be operated under as little
pressure as possible, with the measurement media able to flow freely. If this is not possible, the
sensors can be operated under a constant  pressure of up to 1 bar (relative pressure) or 2 bar
(absolute pressure). Fluctuations in pressure must be avoided.
The membrane cap must only be filled and fully screwed onto the sensor immediately before
inserting it into the flow cell to prevent salt or gel deposits on the inside surface of the membrane.
Touching and contaminating the electrode finger can damage it, making the sensor unusable.
The measurement media must not contain hydrophobic substances (e.g. oil or grease), which can
damage the membrane cap.
The measurement media must not contain surfactants (surface-active substances e.g. from
detergents, cleaning agents or disinfectants).
The presence of air bubbles in the measurement medium in front of the membrane may produce
incorrect measurement results.
If there is no chlorine in the measurement medium for more than 24 hours this will lead to incorrect
measurement results due to biofilm deposits on the membrane. You should avoid operating the
sensors with measurement medium which does not contain chlorine. After operation in a chlorine-free
medium, a settling time period is required before valid measurements can resume.
Using the sensors to measure media containing other oxidants in addition to chlorine, reducing
agents or corrosion protection agents may lead to incorrect measurement results. Refer to the
specifications for each sensor for interfering oxidants and substances.
