Features:
●
Exchangeable microbe electrode units
make operation smoother and less
time-consuming than loading and
replacing conventional membranes.
●
Electrode units may be used for one
month continuously or for three
months intermittently with standard
samples. (Electrode units should be
stored in refrigerators when not taking
measurements.)
●
Front panel allows simple, pushbutton
operation.
●
Ease of replacement by installing
electrode units or tubing into the
opened door in the front panel.
●
Anti-reflux valves and antibacterial
tubing reduce the frequency of
maintenance.
●
Bacteriostatic is mixed into standard
and buffer solutions, so measurements
are stable over the long term.

The Quick BODT-1 takes significant steps to do away with the weaknesses of
biosensor BOD measuring apparatus entailed by trouble and time required
to replace and load microbe membrane and with an exchangeable
electrode. Unit that makes it easy to use right away provides improved
operability and maintainability standard and buffer bacteriostatic solutions
and antibacterial tubing allow stable measurements for long terms The
dedicated shipping and recovery box for Used and replacement electrode
units may be reused any number of times and the exclusion of apparatus
environmentally friendly and easy to use .

BODT-5
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
●
Measurements in regions of low concentration are especially stable.
●
Changing pump rpm or sample contact time allows measurements in regions of high concentration.
●
The optional microbe fixation kit enables the use of other microbes and, therefore, a variety of water samples.
●
Making no use of dangerous reagents and emitting no harmful effluents, the Quick BODT-1 is environmentally friendly.
Biochemical oxygen demand BOD (correspond to the consumption of oxygen in the test bottle) & Gas pressure, such
relevance is dealt with by this instrument, direct display of Biochemical oxygen demand BOD value on the screen.
