Product Introduction
The HM-B04 Pro is the full-configuration flagship of HM Instruments portable water quality analyzer series, delivering four-parameter spectrophotometric detection — Chemical Oxygen Demand (COD), ammonia nitrogen (NH3-N), total phosphorus (TP), and total nitrogen (TN) — in a single field-deployable platform. As the highest-spec model in the HM-B lineup, it enables environmental laboratories and field teams to perform complete nutrient loading assessment without switching instruments or adding supplementary equipment.
Built on the Android 7.1.1 smart operating system with an 8-inch HD touchscreen (1024×768), the HM-B04 Pro features a quad-parameter spectrophotometric detection system that accepts 16mm pre-made test tubes and cuvettes up to 50mm. A 360° precision rotating holder ensures optical measurement stability across all four wavelength channels. The built-in dual-zone 8-hole digester heats from room temperature to 165°C within 10 minutes under intelligent PID control (±0.5°C), with 6 preset digestion programs and 4 custom modes to handle diverse sample matrices.
Four sensor interfaces support simultaneous electrode measurements — pH, dissolved oxygen (fluorescence method), conductivity, turbidity, and dozens of additional parameters — alongside the four spectrophotometric tests. Powered by a 48V 8Ah lithium battery delivering over 6 hours of combined digestion and detection operation, the HM-B04 Pro serves as a complete mobile laboratory for regulatory compliance monitoring, environmental impact assessment, and comprehensive water quality management programs.
