the pH value at the middle point, within the range from pH 7.0 to 7.4. Outside
these
ranges of pH, side reactions occur on the surface of the electrode which
prevent the readings generated from being corrected.
3.2.2.1- Indications
STATUS INDICATOR LED
Fixed blue Led: normal operation
Quick flashing blue Led (2Hz): automatic cleaning
Slow flashing blue Led (1Hz): Stabilization time after cleaning.
Fixed red Led: reading outside measurement range
3.2.2.2- Installation
The sensor should be installed where a
constant flow of water is guaranteed, without
the possibility for forming air bubbles in the
measuring cell.
It is recommended to install it in the
Multifunction sensor holder (ref. 44-020), which
is especially designed for this application. It
includes:
1 Flow controller
2 Inlet filter
3 Sampling device
4 pH sensor housing
5 Amperometric probe housing
3.2.2.3- Stabilization of the probe
After downtime or if it is connected for the first time, the sensor
requires conditioning time. Before calibrating the sensor, place it correctly in the
sensor holder, and let water containing free residual chlorine run through for 1
hour, in order to correctly polarize the cell.
If the sensor has been working at 0, without a water flow,
or without water for 1 hour or more, you will have to wait for 60
minutes for the correct polarization of the sensor and to have a correct reading.
The sensor can be passivated if it has been working at over 3 ppm
for hours. In this case, the sensor should be cleaned in an
HC10. 1M solution for 20 seconds. The sensor can then be prepared and
calibrated again.
