SECTION 9 MAINTENANCE
9.1 CLEANING AND STORAGE
The single most important requirement for accurate and reproducible results in conductivity
measurement is a clean cell. A dirty cell will change the conductivity of a solution by contaminating
it.
NOTE:
ALWAYS RINSE THE CONDUCTIVITY CELL WITH CLEAN WATER AFTER
EACH USE.
To clean the conductivity cell:
1.
Dip the cell in cleaning solution and agitate for two to three minutes. Any one of the foaming
acid tile cleaners, such as Dow Chemical Bathroom Cleaner, will clean the cell adequately.
When a stronger cleaning preparation is required, use a solution of 1:1 isopropyl alcohol and 1
N HCl. Remove the cell from the cleaning solution.
2.
Use the nylon brush (supplied) to dislodge any contaminants from inside the electrode chamber.
3.
Repeat steps one and two until the cell is completely clean. Rinse the cell thoroughly in
deionized, or clean tap water.
4.
Store the conductivity cell in the meter storage chamber.
NOTE: See Section 11, Dissolved Oxygen Probe Precautions for instructions on cleaning the
dissolved oxygen electrodes.
