Portable COD Analyzer for Industrial Wastewater Organic Pollution Monitoring

Portable COD Analyzer for Industrial Wastewater Organic Pollution Monitoring HM-SCOD

HM-SCOD
For facilities monitoring only COD in wastewater discharge permits, the HM-SCOD eliminates the cost of unused multi-parameter capability — delivering HJ/T399-2007-compliant spectrophotometric COD measurement across four ranges at a price point 80% below comparable international instruments.
Handheld COD and Ammonia Nitrogen Analyzer for Wastewater Treatment Monitoring

Handheld COD and Ammonia Nitrogen Analyzer for Wastewater Treatment Monitoring HM-S102

HM-S102
Wastewater treatment facilities whose discharge permits require only COD and ammonia nitrogen reporting can replace two separate instruments with the HM-S102, saving 37% on equipment costs while covering both parameters with laboratory-grade spectrophotometric accuracy in a single 325-gram handheld device.
Portable COD, Ammonia Nitrogen and Total Phosphorus Analyzer for Municipal Wastewater Compliance

Portable COD, Ammonia Nitrogen and Total Phosphorus Analyzer for Municipal Wastewater Compliance HM-S103

HM-S103
Municipal wastewater treatment plants monitoring COD, ammonia nitrogen, and total phosphorus for daily operational compliance can deploy the HM-S103 as a single-device solution — covering the three most critical discharge indicators at 54% lower equipment cost than three separate analyzers, with integrated smart digestor for on-site sample preparation.
Handheld Multi-Parameter Nutrient Analyzer for Discharge Permit Compliance Testing

Handheld Multi-Parameter Nutrient Analyzer for Discharge Permit Compliance Testing HM-S104

HM-S104
Facilities required to monitor COD, ammonia nitrogen, total phosphorus, and total nitrogen under discharge permits can replace four separate instruments with the HM-S104 — covering all four standard compliance parameters in a single 325-gram handheld device at 60% lower total equipment cost, with integrated smart digestor for complete on-site sample preparation.
