4.9 Dissolved oxygen
4.9.1 General information
You can measure the following parameters:
z D.O. concentration
z D.O. saturation index ("D.O. saturation")
z D.O. partial pressure
Note
The sensor connection and the USB-B (device) interface are galvani-
cally isolated. This facilitates interference-free measurements also in
the following cases:
z Measurement in grounded test samples
z Measurement in one test sample with several sensors connected to
one Multi 3430
Temperature
measurement
IDS D.O. sensors measure the temperature with a temperature sensor
integrated in the IDS sensor.
Preparatory activities Perform the following preparatory activities when you want to measure:
Note
The FDO
®
925 needs to be calibrated in special cases only. Regular
FDO
®
Checks are sufficient.
1 Connect the D.O. sensor to the meter.
The D.O. measuring window is displayed.
2 Check or calibrate the meter with the sensor.
