操作原理
GLI差分ORP/pH传感器基于差分电极测量技术，使用三个测量电极取代传统pH 传感器中的双电极。测量电极和标准电极测得的pH值相对于第三个溶液背景电极的差分值。同时利用前置放大器来放大每个电极的输出，电流信号转化为水样的pH值，即是pH值传感器的测量结果。
应用行业
GLI差分ORP/pH传感器适用于石油、制药、造纸等工业过程监测；测量、显示和传输水处理过程中的pH值和温度。
特性和优点
● GLI差分 ORP/pH传感器采用差分技术，三电极取代传统pH传感器的双电极，减少漂移和误差，结果准确可靠。
● 内置的前置放大器，抗干扰能力强，pH传感器输出信号高保真。
● GLI差分 ORP/pH传感器可选择Ryton或PEEK材质测量特殊水样。Ryton材质pH传感器与强碱性物质有良好的兼容性，降低维护与停机时间。PEEK材质pH传感器，降低热曲变。
● 内置可现场更换的盐桥，延长GLI差分ORP/pH传感器寿命。
● pH值传感器适配哈希sc200或sc1000通用控制器，即插即用，多种安装方式可供选择。
● 选配自清洗组件
