DISSOLVED OXYGEN PROBE
Introduction
This instruction sheet provides information on the Hach Dissolved
Oxygen Probe for use with the sens
ion
™
6 Dissolved Oxygen Meter.
The Dissolved Oxygen Probe is a Clark-type amperometric sensor used
to measure dissolved oxygen in aqueous solutions. It consists of an
anode/cathode electrode system and potassium chloride-based
electrolyte, separated from the sample by a replaceable oxygen-
permeable Teflon membrane. A built-in thermistor provides automatic
temperature compensation when using the sens
ion
6 Dissolved
Oxygen Meter.
