SM21, SR20 and SM60 CE Declaration Statement

Yokogawa has invested considerable design and development time in producing a full range of fittings with particular emphasis on designs that reduce installation and maintenance time and consequently save operation costs.

The immersion fittings are designed for either pH or ORP (Redox) measurements in tanks, open vessels and drains. They have a "hoisting cable" for easy maintenance.

很难使用传统pH分析仪获取准确可靠的读数，但是使用合适的设备即可实现稳定准确的纯水pH值测量。横河电机的专用bellomatic pH传感器是高纯水应用的理想解决方案。对于不想维护填充型传感器的用户，FU24是理想的解决方案。它将已成功获得专利的波纹管系统融入到了一体化本体中。

pH电极和传感器是进行pH值测量的传感部分，有伸缩式、流通式、浸入式和直插式等多种安装选项。选择合适的pH电极/传感器对优化测量结果至关重要。
