Self-Cleaning Residual Chlorine Sensor for Industrial Water

CL20-CC self-cleaning residual chlorine sensor features internal cleaning beads for automatic, maintenance-free, high-precision monitoring in industrial water applications.

● Hydrodynamic Self-Cleaning Technology: Driven by the natural impact of water flow, internal cleaning beads continuously collide with the working electrode. This innovative mechanical action automatically prevents the attachment of pollutants without requiring external power.
● Dedicated Electrode Protection Cover: Equipped with a specialized engineered shield that not only houses the cleaning bead mechanism but also protects the sensitive core measurement components from physical damage in harsh industrial environments.
● Maintenance-Free Operation: By actively stopping contaminant build-up, the automatic cleaning process drastically reduces the need for frequent manual probe scrubbing and recalibration, significantly lowering long-term labor and maintenance costs.
● Sustained High-Precision Measurement: Because the working electrode remains continuously clean, the sensor eliminates data drift caused by fouling, guaranteeing highly stable and accurate residual chlorine readings over extended periods of continuous online monitoring.

Self-Cleaning Free Chlorine Sensor Key Features

Manufactured by LOOTEST, the Self-Cleaning Residual Chlorine Sensor for Industrial Water (model CL20-CC) delivers maintenance-free, continuous monitoring for demanding environments. This advanced industrial chlorine sensor utilizes innovative hydrodynamic cleaning beads enclosed within a dedicated protective cover. As water flows, these internal beads continuously strike the working electrode, automatically preventing pollutant attachment and eliminating data drift. Designed specifically for facility managers and water treatment engineers, it effectively solves the costly challenge of frequent manual probe scrubbing. Featuring a rugged structural design with standard pipeline mounting dimensions, it guarantees stable, high-precision measurement.
