Measuring / Operation CellOx 325

4 Measuring / Operation

4.1 Calibration

Note

For calibration, please refer to the operating manual of the measuring instru-

ment.

4.2 Measuring

Please note the required minimum immersion depth and minimum flow (see

chapter 7 T

ECHNICAL DATA).

The minimum flow can be provided in different ways, e. g.:

l The flow velocity of the water to be measured is sufficient (aeration tank,

water pipe, stream)

l Slowly pull the sensor through the water by hand (lake, container), or

l Use a flow aid, e. g. a magnetic stirrer with stirring device (see chapter 8

EAR PARTS AND ACCESSORIES)

4.3 Storage

Always store the sensor in the calibration vessel at a temperature of 0 to

+50 °C. Make sure that the sponge in the calibration vessel is always moist.

Calibration vessel,

OxiCal

-SL

Moisten the sponge:

l Remove the cap (1).

l Take out the sponge (2), wet it, then slightly squeeze it out.

l Reinsert the sponge and close the calibration vessel with the cap.
