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 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 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.
