简要说明：日本横河YOKOGAWA ZR202S直插式防爆型氧化锆氧分析仪

日本横河YOKOGAWA ZR202S一体式防爆型氧化锆氧分析仪

ZR202S是一体型分析仪，集探头和转换器于一身。两种氧化锆氧分析仪都无需采样设备，并可直接将探头安装在烟道壁或炉体中，以测量烟气中的氧气浓度。转换器显示锆池温度和锆池电动势，以及氧气浓度。该分析仪最适用于监视燃烧，并控制性环境下各种工业炉中的低氧燃烧，如炼油厂、石化厂和天然气厂。

特性：

l         嵌入式探头加热设备可现场更换，降低了维护成本。

l         探头采用使用寿命长、可靠性高的氧化锆传感器。

l         分体型转换器ZR402G具有LCD触屏，易于操作。

l         一体型ZR202S集探头和转换器于一身，以减少配线、管道和安装成本。ZR202S单元采用光学开关，易于现场操作。

l         使用数字通信(HART)进行远程维护，降低维护成本。
