Maintenance and storage of electrodes

This section describes an overview of the procedures for maintenance and storage of pH, ORP
and conductivity electrodes.

●

How to clean the electrodes

Always clean the electrode with deionized water after every measurement. When the response
is slow or residue from the sample adheres to the electrode, use the appropriate method below
to clean the electrode, and then clean again with deionized water.

For pH electrode

For ORP electrode

For conductivity electrode

Type of dirt

Cleaning solution

General

Diluted neutral cleaning solution

Oil

Alcohol, or diluted neutral cleaning solution

Inorganic substance

1 mol/L HCl or electrode cleaning solution

Protein

Cleaning solution including protein-removing enzyme

Alkali

Dip in 1 mol/L HCl or electrode cleaning solution for 1h to 2 h

Type of dirt

Cleaning solution

General

Dilute neutral cleaning solution (General dish washing liquid
works reasonably well.)

Oil

Inorganic substance

Immerse dilute nitric acid (1:1 nitric acid)

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 or dilute neutral
cleaning solution. If this does not remove the scale, use diluted
solution that contains oxygen bleach (sodium percarbonate) or
chlorine bleach (sodium hypochlorite).
