Precautions and warnings
Remove the black rubber protection cap from the probe before installing.
Warning: it is strictly recommended not to remove the interchangeable cap
from the probe unless there is a malfunction of the probe itself due to
the luminophore and is absolutely necessary to replace the glass containing
the polymer (see figure below):
Furthermore, it is necessary to pay particular attention to the substances
with which the part of the probe deputed to measurement can come into
contact: for example, organic acids such as acetic acid does not affect the
sensor. However, avoid the exposure of the luminophore in organic
solvents such as acetone, chloroform, benzene and
toluene.Chlorine gas can even destroy the sensor or otherwise affect the
measurements.
The replacement of the luminophore cap is performed while the measures are
not reliable even after calibration.
If the luminophore has some damage on the black surface it is mandatory to
change the cap.
Pay special attention to the formation of air bubbles: these may
interfere with the oxygen measure. To overcome this problem, use the
kit of inclination to 45° of the probe, so that the bubbles can slip
upward.
