6 Maintenance
6.1 Cleaning
Simple cleaning is not sufficient for the probe and measuring device of the pH meter
TR26. Please disinfect the device before and after each use as described in chapter
6.2.
Always spray a pump of NAWAlution into the protective cap before placing it on the
probe tip.
The charging station of the pH meter is NOT waterproof. Avoid direct contact
with water or any other liquids.
6.2 Disinfection
Only use mikrozid® sensitive liquid from Schülke & Mayr for disinfection (see chapter
8 Accessories).
Disinfect the device carefully before and after each use to prevent germ spreading.
Be sure to comply with the exposure time of 5 minutes. Only then can a germ-free use
of the pH meter be guaranteed.
Application:
Fill a test tube with disinfectant (6 ml max.).
Insert the probe without the protective cap for 5 minutes.
Apply the disinfectant to a sterile gauze and clean the meter and, if necessary,
the charging station.
Gently dab the probe tip with a sterile gauze.
Then spray the probe tip with NAWAlution.
You can now use the probe for another measurement (see chapter 5.2.2).
Before storing, always spray a pump of NAWAlution into the protective cap so
that it can be easily removed before the pH meter's next use!
