DMT 820MO, User Manual, Page: 19 / 41

The 820MO system has a build-in pH meter and a pH-meter
electrode plug-in port marked PH on the backside of the 820M
interface.
The pH electrode can be ordered at DMT by contacting your sales
representative or emailing sales@dmt.dk.
The pH calibration procedure is listed in 4 individual steps and needs
to be performed one at a time.
Step 1 - Step 1 involves cleaning the pH electrode and the temperature
probe with double distilled water. When ready, Press NEXT STEP.
Step 2 - Place the pH electrode and temperature probe in the high
buffer solution (here pH 7) and turn on stirring of the high buffer
solution. When the relative pH output in the blue line is stable, go to
NEXT STEP.
Step 3 - Place the pH electrode and temperature probe in the low
buffer solution (here pH 4) and turn on stirring of the low buffer
solution. When the relative pH output in the blue line is stable, go
to NEXT STEP.
