Maintenance and storage

This section describes maintenance of OAKTON 300 handheld water quality meters and each
sensors  used  with  the  meter.  To  use  them  for  a  long  period,  perform  the  described
maintenance  procedures  appropriately.  For  the  detailed  procedures  for  maintaining  and
storing electrodes, refer to the instruction manual for each electrode. This section describes
an overview of the procedures for maintenance and storage to be performed as part of daily
use.

Maintenance and storage of the instrument

How to clean the instrument

If the instrument is dirty, wipe it gently with a soft dry cloth. If it is difficult to remove the
dirt, wipe it gently with a cloth moistened with alcohol.
The  instrument  is  made  of  solvent  resistant  materials  but  is  not  resistant  to  all
chemicals.
Do not dip the instrument with polishing powder or other abrasive compound.

Environmental conditions for storage

Temperature: 0°C to 45°C
Humidity: under 80 % relative humidity and free from condensation

Avoid the following conditions:

Dusty place
Strong vibration
Direct sunlight
Corrosive gas environment
Close to an air-conditioner
Direct wind
