SRB-5 Pressure Difference Method BOD Tester

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.

Features:
#1 Operability and Maintainability

Exchangeable microbe electrode units make operation smoother and less time-consuming than loading and replacing conventional membranes.
Once mounted, electrode units may be used immediately.
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.
Compact size, taking up little space.
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.
#2 Stability
Bacteriostatic is mixed into standard and buffer solutions, so measurements are stable over the long term.
Measurements in regions of low concentration are especially stable.
High correlation with officially certified methods.
#3 Applicability
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.
#4 Environmental Friendliness
Making no use of dangerous reagents and emitting no harmful effluents, the Quick BOD SRB-I is environmentally friendly.
Used electrode units are recovered with a dedicated shipping and recovery box, and replacement electrode units are shipped with the same dedicated box.
Application areas

Determination applies to surface water and domestic sewage, industrial effluents in the BOD.

SRB-1 Quick BOD Tester

Advanced technology Principle

An oxygen electrode monitors the change in respiratory action caused by the consuming of organic matter by bacteria. The bacteria (trichosporon cutaneum) are incorporated into the oxygen electrode. When a solution containing organic matter is fed to the microbe electrode sensor, the microbes ingest the organic matter, increasing respiratory action and in turn the consumption of oxygen. The amount of oxygen passing through the microbe membrane decreases resulting in a change in the current, which is output by the dissolved oxygen electrode. This change corresponds to the concentration of organic matter.

The Quick BOD SRB-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 andwith an exchangeable electrode unit that makes it easy to use right awayprovides improved operability and maintainability standard and buffer bacteriostatic solutions and antibacterial tubing allow stable measurements over the long term. 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 .

Principle of Microbe Electrode Measuring Method
Apparatus for the estimation of biochemical oxygen demand (BOD) with microbial sensor JIS K 3602-1990 (established Sept.1, 1990) although the BOD (JIS K 3602) microbe electrode method and BOD5 (JIS K 102) 5-day method are different, the expected BOD5 value can be approximated from the BOD value. This enables water quality to be monitored over a short period of time in order to permit any necessary measures to be enacted as separate standard.
