Electrode Maintenance and Replacement
•
Rinse the electrode thoroughly with deionized water after use.
•
Do not touch the platinum black coating on sensor surface and always keep it clean.
•
If there is a build-up of solids inside the sensor, remove very carefully, then recalibrate the tester.
•
If you do not use the tester for long periods, store the electrode with tap water.
Replacing the Electrode
If the tester fails to calibrate or gives fluctuating readings, the electrode needs to be replaced.
1.
Twist the electrode collar counter clockwise, pull the electrode away from the tester.
2.
Align the slot on the new electrode, gently push the electrode into the tester.
3.
Twist the electrode collar clockwise until tight.
Appendix
Preparation of Conductivity Standard Solution 146.5 µ S/cm
1.
Place the analytical grade potassium chloride (KCl) reagent in a beaker and dry in an oven for about 3 hours at 105° C/221° F, then cool to
room temperature.
2. Accurately weigh out 74.4
mg of reagent and dissolve in 1 litre deionized water.
3.
Prepared standard solution should be stored in hermetically sealed polyethylene bottle and avoid direct sunlight.
