Principle of Operation
The instrument is designed by the pressure-difference method, simulating the
degradation of natural organic matter. 21% of the oxygen in the air on the top of
Test Bottle continuously replenish the dissolved oxygen consumed in water, carbon
dioxide (CO2) produced in the process of organic matter degradation is absorbed
by Sodium hydroxide coming from sealed cap, pressure sensor monitor constantly
the pressure change of sample bottle. There is a correlation between Biochemical
oxygen demand BOD (correspond to the consumption of oxygen in the test bottle)
and Gas pressure, such relevance is dealt with by instrument, display directly
Biochemical oxygen demand BOD value on the screen.
