Operation
Temperature Measurement
Note: Since most of the M4S sensor is made of plasc material, the sensor should never be used in water samples with
temperatures above 60°C. This would damage the sensor body, the right to claim under warranty would be lost.

Storage of the Sensor
Note: The sensor must never be stored in a so-called zero soluon! This would damage
the electrode and void the warranty.
Refilling of Electrolyte
Note: If the electrolyte comes into contact with your skin, rinse the aected part
immediately under running water.

Replacement of the Cathode Membrane
Note: Never use a needle or other sharp objects to create ow, since the white
wick-like insert would otherwise be damaged! Doing this voids the warranty.

Sensor Refurbishment
Steps for replacing the electrolyte and the cathode-membrane:
Note: If the electrolyte comes into contact with your skin, rinse the aected part
immediately under running water.
Note: Never use a needle or other sharp objects to create ow, since the white
wick-like insert would otherwise be damaged! Doing this voids the warranty.
Note: Wait at least 30-45 minutes before carrying out recalibraon. For accurate
measurements it is recommended to leave the sensor overnight to stabilise and then
recalibrate the next day. The waing period is necessary because the Teon material of
the membrane expands slightly during ng, but will always shrink back to its original
size. This is also indicated by the liquid-crystal display. Immediately aer sensor
refurbishment the value is relavely high and then falls progressively over me.
Please read the relevant secons of this manual with regard to the special points to be
observed when changing the electrolyte or the membrane.
