YOKOGAWA Integrated and Separate Type In Situ Zirconia Oxygen/High Temperature Humidity Analyzer ZR202G/ZR402G

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 fl ue 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
concentration.
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 combustion.
Separate type and integrated type Zirconia High Temperature Humidity Analyzers are used to measure the humidity of hot gases continuously in driers which use an electrical heater or hot gas as the heat source. They can also be used in a variety of manufacturing
applications in humidifi ers, as well as in driers, for humidity measurement and control. They can help improve productivity in these application fi elds.

Features:

• The built-in heater assembly of the probe can be replaced on site, reducing maintenance costs.
• The probe uses a long-life, high-reliability Zirconia sensor.
• The probe uses three-reference gas supply methods (natural air convection, instrument air, and pressure compensated) in its applications.
• The separate type converter incorporates a LCD touchscreen for ease of operation.
• This converter can be used as an oxygen analyzer as well as a high temperature humidity analyzer.
• The integrated type integrates both probe and converter, to reduce wiring, piping, and installation costs. This type of unit uses an optical switch for ease of operation at the site.
• Remote maintenance using digital communications (HART) reduces maintenance costs. *1

Separate Type Converter (ZR402G)

Complete Operation Display
Interactive operations along with operation
display
A variety of display modes – enabling you to
select the operation mode freely
Back-lit LCD allows viewing even in the
darkness
Error codes and details of errors can be
checked in the field without the need to refer to
the appropriate instruction manual

Self-testing suggests countermeasures
for problems

If a problem occurs, the liquid-crystal display will
provide an error code and the reason for the
problem. This enables prompt and appropriate
corrective action to be taken.
