The DO30 sensor for dissolved oxygen is designed for
use in water treatment plants such as sewage treatment
works, effluent activated sludge process, and potable
water treatment. It is also effective in river monitoring, intake
protection, fish farming and other fields where water
quality is important.
This galvanic cell has a fast response time and good long
term stability, and features replaceable diaphragm and
cable for easy maintenance. A temperature sensor is incorporated
for compensation. The DO30 sensor can be used
in either the PB30 floating ball fitting or in the FD30 immersion
fitting.
The PB30 floating ball holder for the DO30 features a
design which minimises fouling by the process. A brass
ring around the sensor facilitates a check for membrane
integrity, and helps to eliminate any deposits of algae,
making a cleaning system unnecessary for the model
PB30. Maintenance is very simple, with only periodic
inspection and calibration needed.
The FD30 PVC immersion fitting is designed for installing
the DO30 sensor in tanks, open vessels and drains. It can
be supplied in lengths between 0.5 and 2.0 metre. Flange
mounting is also possible.
In applications with a heavy load of solids the use of a cleaning
system is recommended, so an option, a “jet
cleaner” is available for the immersion fitting. The use of
this device can extend the continuous measurement period
and eases maintenance.
