Cleaning - Xylem MJK pHix Compact V3 NG Manual

pHix® Compact V3. NG (next generation)
EN 4.10 Version 2202
MJK delivers buffer solutions for both pH and redox calibration.
The pH value of the buffer solution is dependent of the temperature, and the stated pH
value is valid at 77° F / 25° C.
Buffer solution has a limited lifetime. Buffer solution for pH 4 and 7 has a life time of app.
one year, and buffer solution for pH 10 a somewhat shorter lifetime.
Note! Buffer solution with pH 10 is more unstable than the buffer 4.01 and 7.00 and
should therefore be disposed of no later than 10-15 minutes after it has been poured
from the bottle.

Cleaning

Before starting buffer adjustment, wash the electrode in running drinking water and
wipe it with a cloth before immersing it in the buffer solution. Washing and wiping must
be repeated between each step of the buffer adjustment.
Use only fresh buffer solutions! Dispose of any used buffer solution.
Observe that transmitter, electrode and buffer solution has the same temperature -
preferably app. 77° F / 25° C.
