3.4 Dissolved Oxygen Probe Information
The DO 6 palm top meter is supplied with a
Dissolved Oxygen Probe that works on galvanic
principle, that is, it does not require any
polarising voltage from your meter. Rather it will
generate a millivolt signal proportional to the
amount of oxygen in the solution.
Your DO Probe has a twin cable, one with a
BNC connector for the DO measurement input,
and the other with a phono jack plug for the
temperature measurement input. Its sensing
area consists of a cathode, anode, and an inner
electrolyte which is separated from your sample
solution by an oxygen permeable membrane
pre-membraned to the probe’s detachable cap.
Re conditioning of your probe is made easy with
the introduction of this specially designed
detachable pre-membraned cap.
This light weight probe (93X233912 /35642-50)
has a built-in temperature sensor for Automatic
Temperature Compensation (ATC) with 12mm
diameter epoxy body housing and 16 mm
diameter Noryl detachable cap. Its compact
sensing area reduces air entrapment which
makes it easy to obtain fast, accurate and
stable readings. Simply stir the probe in the
solution being measured. Shaking will aid to
remove bubbles if needed before taking a
reading. Also, always ensure to remove water
drops from the membrane when calibrating in
air.
Proper use of probe is essential to ensure that
the optimum measurement is taken in a short
