AH-800 Online Water Hardness and Alkali Analyzer

图片
Online W ater H ardness /Alkali   A nalyzer Model:AH-800 Online Water hardness and Alkali analyzer monits water total hardness or carbonate hardness and   total alkali  fully automatically via titration. Description Th is   analyzer  can measure water total hardness or carbonate hardness  and total alkali fully automaticlly via titration. This instrument is suitable for recognising levels of hardness, quality control of water softening facilities and monitoring of water blending facilities. The instrument allows two different limit values to be defined and checks the water quality by determining the absorbtion of the sample during titration of the reagent. The configuration of the many applications is supported by a configuration assistant. Features ◇ Reliable, exact and fully automatic analysing ◇ Simple commissioning with configuration assistant ◇ Self calibrating and self monitoring ◇ High measuring accuracy ◇ Easy maintenan...
