Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
- BH-485-CHL is a digital online Chlorophyll A (blue‑green algae) sensor from Shanghai Boqu Instrument Co., Ltd. designed for continuous in‑situ measurement of chlorophyll A concentration.
- Compact, submersible probe (Ø37 × 220 mm), IP68 rated, powered by DC 12 V, with standard 10 m cable (extendable to 100 m) and RS485 Modbus RTU output for integration with controllers and SCADA.
Product Features
- Optical fluorescence measurement: emits a specific wavelength LED and detects chlorophyll A fluorescence; intensity is proportional to chlorophyll concentration.
- Wide dynamic range and sensitivity: 0.03–500 µg/L measuring range, 0–500 µg/L full scale, accuracy < ±5%, repeatability ±3%.
- Built‑in optical compensation and ambient light rejection to correct LED drift and minimize interference from external lighting.
- Robust construction: SUS316L for standard use and titanium alloy option for seawater. IP68 waterproof rating.
- Simple calibration (sample or slope calibration) and standard RS485 Modbus RTU communication.
Product Value
- Enables real‑time, continuous detection of algal biomass and early warning of algal blooms to protect drinking water sources, aquaculture stocks, and recreational waters.
- Reduces need for frequent manual sampling and lab analysis, saving time and operational costs while providing faster response to water quality events.
- Integrates easily into remote monitoring systems for automated data logging, alerts, and decision support.
Product Advantages
- Broad measurement range with low detection limit for applications from trace monitoring to bloom events.
- Automatic optical compensation and ambient light rejection improve long‑term stability and accuracy in varied deployments.
- Durable materials and IP68 rating allow deployment in fresh, landscape, and marine environments (titanium option for seawater).
- Standard digital Modbus output and extendable cable support easy integration and remote installation.
- Manufactured with quality control and after‑sales support from an experienced supplier with domestic and international distribution.
Application Scenarios
- Real‑time monitoring at water treatment plant intakes and drinking water source protection.
- Aquaculture farms for managing algal risks to stock health.
- Environmental monitoring of lakes, reservoirs, rivers, coastal waters and landscape ponds.
- Integration into automated SCADA/remote monitoring systems for municipal water utilities, environmental agencies, and industrial water management.
