MBOD METERS

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 threemonths intermittently with standardsamples. (Electrode units should bestored in refrigerators when not takingmeasurements.)

Front panel allows simple, pushbuttonoperation.

Ease of replacement by installingelectrode units or tubing into theopened door in the front panel.

Anti-reflux valves and antibacterialtubing 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 ofbiosensor BOD measuring apparatus entailed by trouble and time requiredto replace and load microbe membrane and with an exchangeableelectrode. Unit that makes it easy to use right away provides improvedoperability and maintainability standard and buffer bacteriostatic solutions

and antibacterial tubing allow stable measurements for long terms Thededicated shipping and recovery box for Used and replacement electrodeunits may be reused any number of times and the exclusion of apparatusenvironmentally friendly and easy to use .

BODT-5

Principle of Operation:The instrument is designed by thepressure-difference method, simulatingthe degradation of natural organicmatter. 21% of the oxygen in the air onthe top of Test Bottle continuouslyreplenish the dissolved oxygenconsumed in water, carbon dioxide(CO2) produced in the process of

organic matter degradation is absorbedby Sodium hydroxide coming from sealedcap, pressure sensor monitor constantlythe 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, suchrelevance is dealt with by this instrument, direct display of Biochemical oxygen demand BOD value on the screen.
