Direct In Situ Zirconia Oxygen Analyzers and High Temperature Humidity Analyzers
This analyzer consists basically of a probe and a
converter that are used as both a Zirconia Oxygen
Analyzer and High Temperature Humidity Analyzer.
The probe is of direct insertion type, and the converter
uses a digital display.
Two types of analyzers are available: separate
type and integrated type. As its name implies, the
integrated type combines probe and converter.
Separate and integrated type Zirconia oxygen
analyzers need not use a sampling device, and allow
direct installation of the probe in the wall of a flue
or furnace to measure the concentration of oxygen
in the stack gas. The converter displays the cell
temperature and cell emf in addition to the oxygen
This analyzer is most suitable for monitoring the
oxygen concentration of combustion gases in large
or small boilers, various industrial furnace and
combustion devices, or for the control of low-oxygen
