Cost-effective Residual Chlorine Meter for Water Drainage

Product Overview

- Cost-effective online residual (free) chlorine meter — model CL-2059H — designed for reliable continuous monitoring of chlorine in water drainage and process waters.

- Wide measurement range: 0.2–500 mg/L (as Cl2) with built?in pH (4.5–8.5) and temperature compensation and no reagent required.

- Compact, low?power instrument (85–265 VAC, ≤4.5 W) with standard industrial communications (RS485 Modbus, two 4–20 mA outputs and high/low relay).

Product Features

- High?range capability up to 500 mg/L for applications with elevated disinfectant concentrations.

- Two?channel measurement with automatic pH and temperature compensation.

- Reagent?free operation using a double gold filmless polymerized reference residual chlorine sensor (constant?voltage measurement principle).

- Multi?output communication and control: RS485, two 4–20 mA channels and relay alarm/control.

- Operating robustness: wide temperature range (sensor -5–60 °C; environment 0–60 °C) and moderate process flow requirement (40–80 L/h).

Product Value

- Low total cost of ownership: reagent?free sensing and stable long?term operation reduce consumable and maintenance costs.

- Improves process control and safety by providing continuous, high?range chlorine data for disinfection and compliance.

- Flexible integration into automation and SCADA via standard outputs for real?time control and alarm management.

- Enables reliable monitoring across diverse industries (drainage, food, aquaculture, industrial water), reducing downtime and protecting downstream systems.

Product Advantages

- Industry?grade manufacturing and QC for reliable, consistent performance.

- Proven constant?voltage sensing technology with pH compensation for accurate free chlorine readings in challenging conditions.

- Wide measurement span (very high maximum concentration) not common in low?range meters.

- Intelligent, multifunctional design with strong environmental adaptability and multiple output options for easy system integration.

- Backed by supplier expertise and responsive customer support.

Application Scenarios

- Continuous online monitoring in water treatment plants and distribution networks (secondary chlorination).

- Cooling tower monitoring and control; pasteurizer dosing control in food processing.

- Seawater chlorination and bromine monitoring; chloramination control in paper and pulp.

- Food and container washing, cold?chain vegetable cleaning, disinfectant control in animal husbandry and biosecurity.

- Wastewater and drainage monitoring where high residual chlorine concentrations may occur and robust, reagent?free measurement is needed.
