Bod Cod Testing Equipment

Biochemical oxygen demand or bod is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period.

Bod cod testing equipment. Hach offers a continually expanding selection of laboratory supplies to cover a range of analytical testing needs. Cod contrasts with biochemical oxygen demand bod which relies on the use of microorganisms to break down the organic material in the sample by aerobic respiration over the course of a set incubation period typically five days. Cod testing also gives the fast measurements required in many treatment systems for informed decisions regarding process control adjustments. Codet 5000 is a new on line automatic analyzer for chemical oxygen demand measurement.

The instrument uses the latest technology such as optical measurement high temperature and high pressure digestion color integration etc has the feature of accurate measurement low detection limit high reliability and good adaptability etc it complies with the relevant testing standards issued by. Meters reagents and equipment for the measurement of some of the key parameters in sewage and effluent testing. Bod and cod correlate with one another in virtually all samples but bod is always lower than cod as the.
