Maintenance and storage of the conductivity cell
For the detailed procedures for maintaining and storing cells, refer to the instruction
manual for each cells. This section describes an overview of the procedures for
maintenance and storage to be performed as part of daily use.
• How to clean the cell
Always wash the cell in pure water (or deionized water) after every measurement. When
the response is slow or residue from the sample adheres to the cell, use the appropriate
method below to clean the cell, and then wash again with pure water (or deionized
water).
• Daily storage of the cell
If the cell is stored in a dry state, the cell constant will change. Store with the black
electrode part immersed in pure water (or deionized water), or with the protective cap
filled with pure water (or deionized water) and attached to the cell.
• When the electrode will not be used for a long period
To store the cell for a long period, wash it well and attach the protective cap filled with
pure water (or deionized water).
Type of dirt
Cleaning solution
General
Diluted neutral cleaning solution
Inorganic substance
Ethanol (keep the ethanol away from plastic parts)
Scale that formed during
long term storage
A commercially available scale remover (neutral cleansing
solution for kitchen use, etc.) diluted by a factor of 100. If this
does not remove the scale, use diluted solution that contains
oxygen bleach (sodium percarbonate) or chlorine bleach
(sodium hypochlorite).
