How to Take Measurements
1.
Conductivity and Temperature Measurements
A. Turn the display module ON by using the left-most key, labeled with the
symbol.
B. Connect a conductivity/temp sensor module to any available port on the
display module.
C. Choose one of the following measurement methods:
Hansen Fittings
Sample Kit –
Mesa P/N 503110017
Syringe Sample tray
Sample Method:
Insert the sensor
end of the conductivity/
temperature sensor module
into the container of test
solution as shown above. Draw
sample solution steadily
through the sensor module.
Note the display output while
the solution is flowing. When
the display is stable, take your
reading.
In-line Method:
Connect condo/temp
sensor module directly to the
delivery system using the
Hansen connectors as shown
above. Reestablish flow
through the sensor module
and take your readings when
the display is stable.
2.
pH Measurements
Module cable connected to 90XL display module
Sample Method:
Insert the pH sensor module electrode into the sample as shown
above. When the display is stable, take your reading.
