®

Maintenance
High-quality metal alloys are used for the contacts between the BOD sensors and the
bottle rack. If necessary, the contacts may be cleaned carefully with a soft cloth.
To compensate for any irregularities and to ensure optimum contact between the BOD
sensor and the bottle rack as well as insuring proper stirring, the BOD measurement
system has 4 levelling screws on its base.
If necessary, the BOD base unit (including the bottle rack) and the BOD sensors can
be cleaned carefully with a soft cloth.
All parts which come into contact with the sample (BOD bottles; seal cups; magnetic
stirring rod) must be cleaned thoroughly after each measurement. The bottles must be
emptied completely and washed several times in hot water.
When any cleaning agents, dish-washing liquids, etc., are used, all parts must be rinsed
thoroughly afterwards! The residues of such agents can interfere with BOD measure-
ments.
