Maintenance and care

High-quality metal alloys are used for the contacts between the BOD sensors and the bottle rack.
Carefully clean the contacts as necessary with a soft cloth.
To smooth out any unevenness, for optimisation of the contact between the BOD sensor and bottle
rack, and for optimisation of the stirrer position, the BOD base unit has 4 adjusting screws on the
bottom.
Carefully clean the BOD base unit (including bottle rack) and the BOD sensors as necessary with a dry
cloth.
The parts coming into contact with the samples (BOD bottle, seal cup, magnetic stir bar) must be
carefully cleaned after each test. Empty the bottles after the testing is complete – observe local re-
gulations in the process – and rinse out repeatedly with hot water. Rinse thoroughly after using
cleansers! Residue from cleansers can destroy the BOD test.
