Dissolved oxygen is needed for the
survival and growth of fish, vegetation, bacteria and aquatic
organisms. The absence of oxygen permits anaerobic decay of organic
matter and the production of toxic material in water. Low levels of
oxygen are normally indicative of serious pollution in fresh and
ground water. In the human environment, water must contain at least
2 mg/L of oxygen to protect water pipes from corrosion. On the other
hand, D.O. can be associated with corrosive and photosynthetic
activity and as a result, it must be excluded from boiler feedwater.
The HANNA instruments® HI 93732N is a custom-made, microprocessor
colorimetric D.O. meter. Pre-standardized reagents are supplied in
liquid form for higher speed and accuracy. To take a measurement,
simply zero your sample and oxidize it with the liquid reagents.
Then, place the cuvet inside the meter and read D.O. from 0 to 10
mg/L in tenths of ppm.
