less than a week. Power consumption is very low and the turbidi

-

meter remains ready for use.

If water hardness is very high, lime deposition may precipitate.

1

Stop sample flow.

2

Switch off power.

3

Empty measuring chamber by turning the manual 5/4 valve to

EMPTY.

4

If necessary clean the measuring chamber (see
