HM-B200M Integrated Water Quality Analyzer with Electrode and Spectrophotometric Detection HM-B200M

Product Introduction

Water quality professionals face a fundamental instrumentation challenge: spectrophotometric methods excel at measuring chemical parameters like COD, total nitrogen, and heavy metals, while electrode sensors provide real-time readings of pH, dissolved oxygen, conductivity, and turbidity — yet these two analytical approaches have historically required separate instruments. This division forces field teams to carry multiple devices, manage separate calibration schedules, and manually consolidate data from different systems.

The HM-B200M resolves this limitation by unifying both detection technologies within a single 11kg portable platform. Its spectrophotometric module covers 49 standardized colorimetric parameters, while the integrated 4-port sensor module simultaneously accepts up to 4 different electrode probes — enabling concurrent measurement of parameters such as pH, ORP, dissolved oxygen (fluorescence method), residual chlorine (constant voltage method), conductivity, salinity, ozone, turbidity, hardness, suspended solids, sludge concentration, COD, ammonia nitrogen, chlorophyll, blue-green algae, oil in water, and CDOM.

This unified architecture delivers measurable operational advantages. A wastewater treatment plant operator can simultaneously digest COD samples in the dual-temperature-zone 8-hole block, run spectrophotometric ammonia nitrogen analysis through the 360° rotating colorimetric system, and monitor pH and dissolved oxygen via sensor probes — all from one instrument interface. Sensor readings support both timed automatic storage and manual capture, with data exportable alongside spectrophotometric results.

For organizations operating spectrophotometry-only systems like the HM-B100M, the B200M sensor module represents a strategic upgrade expanding analytical coverage without adding equipment complexity.

FAQ

Q: How does the 4-port sensor module work in practice?

Each of the 4 ports accepts a different sensor — e.g., pH, DO, conductivity, and turbidity simultaneously. Results display on a single screen. Data can be captured manually or at timed intervals, useful during sample preparation while digestion cycles run.

Q: What sensor types are compatible with the HM-B200M?

The instrument supports 17+ sensor types including pH, ORP, dissolved oxygen, residual chlorine, conductivity, salinity, ozone, turbidity, hardness, suspended solids, sludge concentration, COD, ammonia nitrogen, chlorophyll, blue-green algae, oil in water, and CDOM. All sensors are plug-and-play with automatic recognition.

Q: Can spectrophotometric and sensor measurements run at the same time?

Yes — the B200M enables spectrophotometric COD analysis through the rotating colorimetric system while simultaneously monitoring pH and dissolved oxygen via sensor probes, all while the dual-zone digester processes additional samples.

Q: How does the B200M compare to using separate handheld meters?

Traditional setups require separate pH, DO, conductivity meters and a spectrophotometer — four instruments with individual calibration and data management. The B200M consolidates all into one 11kg device with unified GPS-tagged storage and cloud upload, reducing total equipment weight from 15-20kg to 11kg.

Q: What training is required to operate both detection systems?

The touchscreen presents both spectrophotometric and sensor workflows through intuitive menus with built-in instructional videos. Most operators become proficient within 1-2 days. Pre-made reagent kits require only adding the water sample for standard parameters.

Q: How does evidence documentation support regulatory compliance?

The 720P camera captures geo-tagged photographs automatically linked to test records with GPS coordinates and timestamps. This creates a complete evidence chain for environmental enforcement agencies, eliminating disputes about sample origin or testing conditions.
