sulfide, sulfur dioxide, and boranes can react at the anode. After
exposure to reducing gases, the user may need to clean the anode
and replace the internal filling solution and membrane cap.
Summary of Method
The sens
ion
156 Meter responds to the dissolved oxygen
concentration activity by developing an electrical current. At a
constant temperature, the electric current varies linearly with the
oxygen concentration of the solution. An increase in temperature
will increase the oxygen diffusion through the membrane
exponentially. The meter utilizes automatic temperature
compensation to ensure accurate results.
The following tables have been provided as a reference, but are
not required for use with the DO meter.
