Yokogawa Zirconia Oxygen Humidity Analyzer ZR22G, ZR802G
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 converter incorporates the LCD touchscreen for ease of operation.
Converter of Zirconia Oxygen Humidity Analyzer ZR22G ZR802G
This converter can be used as an oxygen analyzer as well as a high temperature humidity analyzer.
The deterioration status of the sensor can be confirmed by the sensor resistance check function (self-diagnosis function) in the converter.
The converter records history of alarm on/off, measured value history for up to 40 days, and others.
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, Modbus TCP and RTU) reduces maintenance costs.
