Yokogawa ZR22G-S1-200-S-W-E-T-T-E-A-ZA Zirconia Oxygen Analyzer

The Yokogawa ZR22G-S1-200-S-W-E-T-T-E-A-ZA Zirconia Oxygen Analyzer Detector is an in-situ zirconia oxygen detector designed for continuous measurement of oxygen concentration in combustion gases, enabling real-time combustion control in boilers, furnaces, kilns, and incinerators. Its Style S1 detector uses a zirconia solid electrolyte sensor and is configured as a probe-type analyzer with a 2.0 m probe length (code 200) and stainless steel wetted surfaces (code S). It is installed directly into process gas via an ANSI/JIS equivalent flange (code dependent) and can operate up to approximately 700°C, with higher temperatures achievable using an adapter. It requires an external converter (for example, ZR802G) to provide the electrical output, and features a field-replaceable zirconia cell and heater assembly for maintenance. Applications span industrial combustion processes where continuous oxygen monitoring supports efficiency and emissions control, including boilers, furnaces, kilns, and incinerators. Related replacements include Yokogawa ZR22S explosion-proof detector, ZR202 integrated oxygen analyzer, and ZR402G converter plus ZR22G probe system.
