MW605 Dissolved Oxygen & Temperature Portable Meter
5. MA860 PROBE DESCRIPTION
The
MA860
probe uses a galvanic sensor with a built-in thermistor
that allows stable, temperature compensated readings.
The sensor makes use of a cathode, anode and electrolyte solution,
protected by an oxygen permeable membrane. Oxygen that passes
through the membrane causes a current flow, from which the
oxygen concentration is determined. The membrane is fixed to a
detachable cap that allows for simple replacement and priming.
The probe has a reinforced plastic body for durability.
