HR-200

Field-installation type polarographic residual chlorine meter

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.

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

Achieving stable measurements through two types of cleaning

In addition to continuous cleaning using normal abrasives (cleaning beads), electrochemical cleaning can be performed.
