This project aims to conduct rapid, accurate, and comprehensive assessments of regional water quality through scientific and user-friendly testing methods, providing critical data to support water quality management, pollution control, and ecological conservation within the basin.
ShenZhen Huaju Scientific Instruments Handheld Water Bio-Toxicity Analyzer
Developed by Shenzhen Huaju Scientific Instruments Co., Ltd., this handheld analyzer complies with GB/T 15441-1995 and ISO 11348-3 standards, utilizing luminescent bacteria methodology to detect water toxicity. The device employs bacteria that emit blue-green fluorescence (450–490 nm) during normal metabolic activity. Exposure to toxic substances disrupts bacterial metabolism, suppressing fluorescence intensity in proportion to toxicity levels. This biological mechanism offers a reliable basis for environmental quality assessment. Serving as an efficient on-site complement to traditional physicochemical analysis, the analyzer enables rapid pollution detection in water bodies.
Key Innovations
Dual-light-path dynamic monitoring: Tracks real-time toxicity inhibition kinetics during testing, revealing the full toxicological response process and overcoming limitations of single-measurement evaluations.
Broad detection spectrum: Identifies heavy metal ions, organic pesticides, and toxic organic/inorganic compounds.
Portable and user-friendly: Compact handheld design with a carrying case; requires no specialized biological expertise.
Rapid results: Qualitative toxicity classification within 5 minutes, supported by over 20 hours of standby time for extended field monitoring.
Stable performance: High-quality, non-polluting bacterial strains ensure consistent reliability.
