7.2.4 ORP sensor: REDOX/Temperature.
General Description
Redox : a pair of electrodes with a reference (Ag/AgCl gel) /platinum ring
Temperature : NTC.
Materials
Glass, platinum, PVC, Polyamide, DELRIN; polyurethane jacketed cable.
Safeway
The redox potential electrode is sensitive to sulphide adsorption on platinum.
Measurement/ Interference
During the introduction of sensor in the measurement environment, wait
sensor’s temperature stabilization before proceeding with measurement..
Operating temperature
0°C to 50°C
Maintenance
After each use, rinse meticulously the sensor with clear water.
Clean the platinum ring with an abrasive moist paper (type P1200 or P220).
Storage
Maintain the head of the sensor hydrated in the protection case with a few
drops of preservation agent solution (PF-CSO-C-00005) or, if it is not
available, with the solution of KCl. Rinse profusely the sensor before use.
After storage in dry environment, put the sensor in a KCl solution for 12
hours.
The case protects against direct impact on the head of the sensor.
Storage temperature
0°C to + 60°C
Redox verification
Using a clean sensor, check the electronic 0 by putting the sensor in free air
and a second point with standard solution at 240 mV (or 470 mV).
Temperature calibration
Refer to section 7.2.1
Changing the cartridge
To avoid deteriorating the electronic part of the sensor, take the cartridge in
one hand and unscrew the clamping ring with the other hand. Remove the
used cartridge and put the new cartridge before to screw back the clamping
ring.
