Ensure the controller has been calibrated. Ensure the D.O. probe is
immersed in the sample to be tested.
The D.O. reading can be displayed in % air saturation or in ppm (mg/L)
according to the range selection switch. The corresponding LED is ON.
For accurate dissolved oxygen measurements a water flow of at least
5-7 cm/sec is required. In this way a constant replenishment of the
oxygen-depleted membrane surface is ensured.
Accurate readings are not possible in still water.
Note:
For some particular applications, such as fish farming, the mem-
brane can be sterilized with stabilized iodine (20 to 50 ppm),
typically used for this purpose.
Note:
For use in harsh environments, it is recommended to protect
the membrane with the optional
HI 76410-0
sleeve. The re-
sponse time will slightly slow down.
