BOQU Cod Analyzer Cod Analyzer High Qualtiy

Product Overview

- The BOQU Cod Analyzer (model TOC-5000) is an online, reagent-free total organic carbon (TOC) analyzer designed for continuous monitoring of organic pollutants in water. It measures UV absorbance at 254 nm using dual UV light sources (one reference) to provide stable, real-time TOC readings. The system includes a transmitter and an IP68 sensor, and supports industrial integration via RS-485 Modbus RTU.

Product Features

- UV 254 nm measurement with two light sources and a UV reference to automatically compensate for optical path attenuation and turbidity.

- Wide measurement range: 0–200 mg/L (with auto-clean brush) and up to 0–800 mg/L (with air-pump cleaning).

- High resolution (0.1 mg/L) and accuracy (~±5%).

- Outputs: RS-485 (Modbus RTU), 4–20 mA analog output, and two relay contacts.

- Rugged construction: TOC transmitter IP65, sensor IP68; operating temperature 0–60°C; panel hole size 138 × 138 mm.

Product Value

- Enables continuous, real-time process control of organic contamination without chemicals or reagents, improving operational responsiveness and compliance.

- Digital connectivity (Modbus RTU) allows direct integration with PLCs and HMIs, reducing I/O and system integration costs.

- Low maintenance options (auto-clean brush or air pump cleaning) and automatic optical compensation enhance measurement reliability and reduce downtime.

Product Advantages

- Stable, drift-free performance thanks to dual-light UV design and automatic compensation for turbidity and path attenuation.

- Flexible deployment with a wide dynamic range (up to 800 mg/L) to serve diverse water types and pollution levels.

- Proven industrial interfaces and protections (RS485, 4–20 mA, relays, IP68 sensor) for robust field use.

- Easy operation and maintenance with clear display and straightforward installation.

- Manufactured by BOQU Instrument (Shanghai), backed by technical support and a stated rapid response policy.

Application Scenarios

- Municipal and industrial wastewater treatment plants for process control and discharge monitoring.

- Industrial effluent monitoring in sectors such as pharmaceutical, chemical, food & beverage, petrochemical, and textile.

- Cooling water and boiler feedwater monitoring in power plants and manufacturing to detect organic fouling.

- Water reuse and reclamation facilities to ensure organic load targets are met.

- Environmental monitoring of surface waters and compliance testing where continuous organic carbon tracking is required.
