CU-500 Total Organic Carbon (TOC) Analyzer Module
Product Overview
The CU-500 Total Organic Carbon (TOC) Analyzer Module is a high-precision water quality testing device that utilizes UV lamp static oxidation to analyze water samples. During testing, the water sample is fully isolated in a closed chamber to prevent environmental contamination and ensure accurate results. The TOC value is determined by measuring the conductivity changes before and after oxidation, reflecting the organic carbon content in the water.
The compact CU-500 module can be seamlessly embedded into pharmaceutical water systems, semiconductor ultrapure water preparation systems, and power plant deionized water monitoring. It supports RS485 and RS232 communication, with optional 4-20mA output, touchscreen, data storage, and printer modules for flexible industrial automation applications.

Key Features
•High Detection Accuracy: Wide measurement range with TOC detection as low as 0.1 µg/L and repeatability ≤3%, ensuring precise water quality monitoring.
•Compact and Lightweight: Dimensions 12cm × 5.6cm × 22cm, weight only 2 kg, ideal for embedding in existing equipment.
•Low Maintenance: No carrier gas or chemical reagents required, reducing operational cost and simplifying maintenance.
•Flexible Communication: Supports RS485/RS232 and optional 4-20mA output for integration with industrial control systems.
•Expandable Functionality: Optional 3.5-inch touchscreen, data storage, and printer for customized monitoring needs.
•Robust Operation: Operates under 0–40°C temperature and ≤85% relative humidity, suitable for diverse industrial environments.

Working Principle
The CU-500 TOC Analyzer Module converts organic carbon in water samples into CO₂ using UV lamp static oxidation. The conductivity change before and after oxidation is directly proportional to the TOC concentration. The closed-chamber design prevents environmental contamination, providing reliable and accurate measurements.
Process Flow:
•Water sample enters the closed detection chamber.
•UV lamp oxidizes the organic carbon in the sample.
•Conductivity sensors measure pre- and post-oxidation water conductivity.
•Data processing calculates the TOC value for real-time monitoring.
