HORIBA’s long-selling water quality meter that excels in indoor applications.
Ideal for measuring the concentration of free residual chlorine in tap water, swimming pools, spas and similar environments. By combining two methods, namely physical polishing cleaning using cleaning beads and electrochemical cleaning utilizing electrochemical reactions, long-term stable measurements can be achieved.
