Product Overview


Model HD-210  1.png

BOQU Industrial 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.
