HM-BL03 Portable COD/Ammonia/TP Analyzer

Product Introduction

The HM-BL03 Portable COD/Ammonia/TP Analyzer from HM Instruments is purpose-built for municipal wastewater treatment plants and environmental monitoring teams that need to measure the three most critical discharge compliance parameters — COD, ammonia nitrogen, and total phosphorus — in a single, portable instrument. Utilizing spectrophotometric detection across three dedicated wavelengths (420, 620, and 700 nm), the HM-BL03 delivers laboratory-grade accuracy at 0.001 Abs absorbance resolution directly at the sampling point. The integrated digestion module enables complete on-site sample preparation for total phosphorus protocols requiring high-temperature persulfate digestion, eliminating the need for external heating equipment. With 4G and Wi-Fi connectivity, built-in GPS positioning, and cloud platform integration, every measurement is automatically tagged with geospatial coordinates and uploaded for centralized compliance tracking. The built-in thermal printer provides immediate hard-copy documentation for audit trails. Weighing 8.3 kg with AC 220V and lithium battery dual power supply, the HM-BL03 is the sweet spot in the HM-BL product line — delivering exactly the three parameters that municipal WWTPs are mandated to report, at a price point significantly below the full multi-parameter models.

Applications

• Municipal wastewater treatment plants — daily monitoring of COD, NH3-N, and TP discharge compliance

• Environmental monitoring stations — surface water quality assessment for eutrophication indicators

• Industrial effluent supervision — chemical, food processing, and paper industry discharge verification

• Discharge permit compliance reporting — NPDES and national permit requirement monitoring

• Third-party testing laboratories — portable on-site verification for municipal WWTP clients

• Construction site stormwater runoff — nutrient and organic load verification

• Agricultural non-point source pollution investigation — phosphorus and nitrogen tracking

• Lake and river eutrophication monitoring — simultaneous organic and nutrient parameter assessment

Functional Performance

1. Three-wavelength LED spectrophotometric system (420/620/700 nm) precisely covering COD, ammonia nitrogen, and total phosphorus measurement requirements.

2. COD detection via dichromate method, ammonia nitrogen via Nessler/salicylate method, and total phosphorus via persulfate digestion–molybdenum blue method.

3. Integrated digestion module for complete on-site sample preparation without external heating equipment.

4. 4G and Wi-Fi wireless connectivity for real-time cloud platform data upload and compliance reporting.

5. Built-in GPS positioning for geotagging every measurement record with location coordinates.

6. Thermal printer for immediate on-site result documentation with tamper-evident output.

7. 0.001 Abs absorbance resolution for precise low-concentration detection across all three parameters.

8. AC 220V and lithium battery dual power supply for both laboratory bench and field deployment.

9. Cloud platform integration enabling remote data access, trend analysis, and automated threshold exceedance alerts.

10. Compact 430 × 350 × 190 mm enclosure at 8.3 kg — portable for single-operator field campaigns.
