工作原理：
9184sc余氯在线检测仪的原理为：电解液和渗透膜把电解池和水样品隔开，渗透膜可以选择性地让ClO-穿透；在两个电极之间有一个固定电位差，生成的电流强度可以换算成余氯浓度。
在阴极上：ClO-+2H++2e-→Cl-+H2O
在阳极上：Cl-+Ag→AgCl+e-
由于在特定温度和pH值条件下，HOCl、ClO-和余氯之间存在固定的换算关系，通过这种方式进行余氯检测。
应用行业：
9184sc余氯在线检测仪适用在饮用水、工业过程水消毒工艺的次氯酸（HOCL）/余氯检测，尤其适用于反渗透等膜处理工艺进水的余氯检测。
仪器特点：
● 9184sc余氯在线检测仪的量程宽且检出限低，满足低量程测量用户的需求。
● 9184sc余氯在线检测仪用选择性膜传感器。
● 9184sc余氯在线检测仪带 pH 和温度补偿，使读数更接近真实值。
● 9184sc余氯在线检测仪内置流量控制装置。
● 维护量小：每两个月校正一次，每六个月更换一次电解液和膜。
● 即插即用：采用电极法，使用的时候只需要插上电极，开机就可以进行余氯检测。
