Product Introduction
The HM-B500 Multifunctional Portable Water Quality Detector is the full-configuration model in the HM-B series, integrating all four analytical modules on a single portable platform: spectrophotometric water quality analysis, voltammetric heavy-metal detection, biological toxicity screening, and ATP hygiene testing. This comprehensive configuration enables a complete water quality assessment workflow — from chemical parameter quantification through trace metal analysis to biological effect evaluation and hygiene verification — without the need for multiple separate instruments.
The spectrophotometric module uses a multi-wavelength LED light source (420–860 nm) with pre-configured analytical wavelengths matched to national standard methods, covering 49 routine water quality items including COD, total nitrogen, total phosphorus, ammonia nitrogen, turbidity, and colorimetric metal indicators. The voltammetric heavy-metal module employs anodic stripping voltammetry with disposable screen-printed electrodes, achieving 0.5 ppb detection limits for cadmium and lead in water samples and 0.01 mg/kg in grain samples. The biological toxicity module uses luminescent bacteria to assess acute toxicity within 15 minutes of sample preparation, with dual-mode testing available (bacterial luminescence for quantitative results, chemiluminescence for qualitative screening). The ATP module delivers hygiene verification in 15 seconds using the firefly luciferin-luciferase system. All four modules are managed through a 15.6-inch Android touchscreen with a unified interface. For users whose monitoring scope is narrower, the HM-B300 covers water quality, toxicity, and ATP, while the HM-B400 covers water quality and heavy metals.
