HM-B300 Portable Water Quality Detector for Environmental Toxicity Monitoring HM-B300

Product Introduction

Environmental monitoring agencies and industrial facilities face a persistent challenge: conventional water quality parameters, biological toxicity, and hygiene indicators typically require separate instruments, each with distinct calibration protocols and data management systems. This fragmentation increases equipment costs, extends field deployment time, and complicates data consolidation for regulatory reporting. The HM-B300 Multifunctional Portable Water Quality Detector addresses this gap by integrating three complementary analytical approaches within a single ruggedized platform.

At its core, the instrument employs multi-wavelength spectrophotometry using a 420–860 nm LED light source system, with analytical wavelengths pre-configured to match national standard methods. Pre-loaded calibration curves enable direct calculation of COD, total phosphorus, total nitrogen, ammonia nitrogen, and 45 additional parameters from the 49-item test library. The biological toxicity module leverages the metabolic luminescence principle: luminescent bacteria emit visible fluorescence proportional to metabolic activity, and when toxic substances are present, the fluorescence intensity decreases in proportion to toxicity. Results are expressed as relative luminosity (%) and equivalent reference toxicant concentration (mg/L), with quantification completed within 15 minutes of sample preparation. The ATP detection module uses the firefly luciferin-luciferase system to measure adenosine triphosphate levels in 15 seconds, providing a rapid indicator of microbial contamination and surface cleanliness.

A built-in 4-position digester with independent temperature control (room temperature to 200°C, ±0.5°C accuracy) enables simultaneous digestion and cooling during measurement, eliminating the need to carry separate digestion equipment. The Android 10 operating system on a 15.6-inch touchscreen manages all three modules through a unified interface, while 800,000-record local storage, thermal printing, Wi-Fi data upload, and USB Excel export support traceable data workflows from field to report. For monitoring programs that also require trace heavy-metal analysis, the HM-B500 full-configuration model extends the same platform with anodic stripping voltammetry for cadmium and lead detection.

Applications

• On-site rapid screening: Deployable at river, lake, and reservoir sampling points for immediate parameter assessment without sample transport delays.
• Emergency pollution incident monitoring: Rapid toxicity screening using luminescent bacteria provides a first-pass assessment of unknown contamination within 15 minutes, guiding response decisions.
• Industrial wastewater compliance: Pre-configured methods for COD, total nitrogen, total phosphorus, ammonia nitrogen, and heavy-metal indicators support discharge permit verification.
• Surface water routine inspection: Field detection at designated monitoring cross-sections for rivers and lakes, with results exported directly for regulatory databases.
• Biological toxicity assessment: Quantitative evaluation of acute toxicity in surface water, industrial effluent, domestic sewage, and emergency incident water samples using dual-mode testing.
• ATP hygiene verification: 15-second cleanliness testing for water treatment plant surfaces, distribution system components, and storage facilities.
• Laboratory comparative analysis: Supports bench-side verification of field results with the same calibration curves and detection methods.
