Yokogawa Zirconia Oxygen Analyzer ZR202G-200-S-E-N-E-R-M-E-A
Features for Yokogawa Zirconia Oxygen Analyzer ZR202G-200-S-E-N-E-R-M-E-A
• 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 touch screen 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.
