The 970 is supplied with a single probe with integrated temperature measurement, allowing automatic temperature compensation as standard.

Biological Oxygen Demand or BOD serves as an indicator of water pollution in water quality management. BOD5 measures the amount of oxygen consumed by aerobic bacteria in the breakdown of organic matter in a sample of water over 5 days in the dark at 20°C. The greater the value, the higher the degree of pollution.

A number of accessories are available for use with the 970, 9150 and 9200 dissolved oxygen meters.
