HR-480

Panel-mount type galvanic residual chlorine meter

A compact water quality meter that offers a wide range of features and functionality.

Ideal for measuring the concentration of free residual chlorine in tap water, swimming pools, spa water, and similar environments. Residual chlorine concentration can be easily measured without the need for reagents.

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

The sensor can be used for an extended period of time

The sensor unit can regenerate the cathode electrode, allowing for long-term sensor usage.
