What is Dissolved Oxygen
(DO)?
Many gases mix with water like
nitrogen and oxygen without chemically reacting with it. Some gases
chemically react with water e.g. ammonia, CO2, and HCl. Oxygen does
not react with water. Dissolved Oxygen (DO) is really a physical
distribution of oxygen molecules in water. There are two main
sources of DO in water: atmosphere and photosynthesis. Waves and
tumbling water mix air into water where oxygen readily dissolves
until saturation occurs. Oxygen is also produced by aquatic plants
and algae as a by-product of photosynthesis.

How Can Dissolved Oxygen be
Measured?
Dissolved Oxygen can be measured in the laboratory using a bench
Dissolved Oxygen analyzer, in outdoor and field applications a portable DO Meter
would be used and for plant and process applications an online DO
controller would be used. Dissolved Oxygen can be measured using the
Polarographic
(Clark Cell) Method or the Galvanic
Cell Method.

Replacement Sensors and
Ancillaries:
At
R.M.S Ltd we can supply replacement DO2 sensors for both Industrial
and Laboratory applications that
are compatible with all modern instruments. All of our
electrochemical sensors can be supplied with or with out temperature
compensation. When it becomes necessary to change the membrane of
our Do probes, it is a simple task to unscrew the membrane cap, fill
a new one with the filling solution provided and screw on to the
probe. All we need is the make
and model of your DO meter so that we can determine the correct
connector etc - please
email,
phone or
fax us with your requirements and one of our team will contact you.
