Cod Bod Analyzer Online COD BOD Analyzer Wholesale - BOQU

Product Overview

- CHG-18 Online Chlorophyll Analyzer (manufactured by BOQU) is an inline, digital sensor system that measures chlorophyll a in water by fluorescence (exciting chlorophyll a with monochromatic light and detecting emitted light). It provides continuous, real?time chlorophyll concentration readings (0–500 ?g/L) for freshwater and seawater environments.

Product Features

- Fluorescence?based measurement principle for direct, reagent?free detection of chlorophyll a.

- Measuring range 0–500 ?g/L with ±5% accuracy.

- Robust materials: SUS316L body for freshwater, titanium alloy option for seawater.

- Communications: RS485 Modbus RTU; outputs include 2 × 4–20 mA and 3 relay outputs.

- Power: AC 85–500 VAC (50/60 Hz) or DC 9–36 VDC.

- Environmental & mechanical: pressure ≤0.4 MPa, working temperature ?15 to 60 °C, transmitter IP65 and sensor IP68.

- Standard 10 m cable (extendable to 100 m), fast response, strong anti?interference and long transmission distance.

- Easy on?site installation, maintenance?free, no sample pre?treatment required.

Product Value

- Enables continuous, real?time water quality monitoring to detect algal blooms and chlorophyll fluctuations quickly—avoids delays and errors from grab sampling.

- Eliminates chemical reagents and secondary pollution, reducing operating costs and environmental footprint.

- Supports process automation and timely decision making (via analog/Modbus outputs and relays), improving operational control and regulatory compliance.

- Durable construction and low maintenance reduce lifecycle costs and downtime.

Product Advantages

- Advanced, standardized manufacturing ensures consistent quality and reliable performance.

- Competitive pricing with strong overseas market reputation.

- High technical maturity and customizable solutions to meet specific customer requirements.

- Corrosion?resistant materials and IP?rated enclosures for long service life in diverse water conditions.

- Digital interface and strong interference immunity for stable long?distance data transmission.

Application Scenarios

- Drinking water plant inlet monitoring and source water protection.

- Water source sites and surface water quality surveillance (rivers, lakes, reservoirs).

- Aquaculture for early detection of harmful algal blooms.

- Landscape/ornamental waters and seawater monitoring (coastal and marine sites).

- Any continuous online monitoring program concerned with chlorophyll / algal levels (environmental monitoring, water treatment, industrial water management).
