Membrane sensor for free
chlorine FC1
The FC1 membrane sensor is a special sensor for measuring the
concentration of chlorine in water. The sensor demonstrates a
slight pH value dependency (see "Technical data“) and is therefore
very suitable for water with various pH values. The sensor may
only be used in clear water of potable water quality.
Commissioning
Caution!
The electrode fingers (D) and membranes (G) are extremely
sensitive! Do not touch, soil or damage! Before unscrewing the
filled membrane cap (E), push the elastomer seal (I) to one side to
permit the inflow of air through the vent (F) underneath it (at the
cap label)! Otherwise, the membrane (G) may be damaged due to
the development of underpressure. Do not remove the light
yellowish-gray deposit of the reference electrode (M) or wipe it in
the direction of the gold working electrode (L)! Flush eyes and skin
immediately with water after contact. Rinse away spilled
electrolyte with water.
1
Screw membrane cap (E) off the electrode shaft (B).
2
Place the membrane cap (E) and the G-holder* (K) on a clean,
non-absorbent pad and fill both with the included electrolyte
bubble-free up to the upper rim.
*) The G-holder (K) will only be used in sensors that were
delivered as of November 2004. The G-holder (K) is not
required for sensors that were delivered up to October 2004.
3
Rub gold working electrode (L) with the included lapping paper
(special emery). To do this, lay the lapping paper on a paper
towel, take hold of a corner, and using the tip of the vertically-
held electrode shaft (B) (without G-holder), slide it once or
twice over the rough side of the lapping paper.
4
Check whether the elastomer seal (I) completely closes the
valve opening (F).
5
Hold the electrode shaft (B) vertically and carefully push the
electrode finger (D) into the filled G-holder (K).
6
Then screw the filled membrane cap (E) slowly (by hand) back
onto the electrode shaft (B).
Please note
As the excess electrolyte escapes through the valve opening (F)
under the elastomer seal (I), do not clamp it shut and do not press
it onto the elastomer seal (I).
