ST600-YG2 Online Optical Gas Oxygen Analyzer
在线气体氧分析仪
测量原理
氧是一种非常有效的荧光猝灭剂，水溶液中的溶解氧对荧光也同样具有猝灭作用，荧光物质的荧光强度或寿命与溶解氧质量浓度的关系可用Stern-Volmer动态荧光猝灭方程描述为：F0/F=1+K*C，式中F0与F分别为体系在无氧和有氧状态下测得的荧光强度，K称为Stern-Volmer常数，C为溶解氧的浓度。
主要特点
- 高精度：溶解氧检测精度最高达1μg/L（ppb），分辨率最高达0.1μg/L（ppb）
- 响应快：从空气中饱和氧浓度8mg/l测量到5μg/L（ppb）级只需5分钟
- 多用途：气体氧、溶解氧均可测量，原位式、流通式测量均可
- 实时、历史曲线显示：实时测量值与曲线同步显示，历史数据曲线显示
- 1-2道设置：可选1-2路溶解氧或气体氧传感器接入，为客户节约成本
- 维护方便：电极维护只需更换膜片，几乎免维护
- 大容量数据存储：可存储320万条数据，历史曲线查询功能
- 高防护等级：IP65
- 质保期：1年
