HM-SCOD Handheld COD Detector

HM-SCOD Handheld COD DetectorHM-SCOD

HM-SCOD
The HM-SCOD is a dedicated single-parameter handheld COD detector covering 10–15,000 mg/L across four measurement ranges, compliant with HJ/T399-2007. Its Android OS interface, automatic wavelength selection, and 0.001 absorbance sensitivity deliver laboratory-grade spectrophotometric accuracy at the lowest price point in the HM Instruments handheld water quality detector lineup.
HM-S102 Handheld COD and Ammonia Nitrogen Detector

HM-S102 Handheld COD and Ammonia Nitrogen DetectorHM-S102

HM-S102
The HM-S102 combines COD and ammonia nitrogen measurement in a single handheld device, covering the two most frequently monitored wastewater discharge parameters. At $810, it costs 37% less than purchasing separate HM-SCOD and HM-SNH-2 units, while retaining the full Android OS interface, automatic wavelength selection, and included smart digestor.
HM-S103 Handheld COD, Ammonia Nitrogen and Total Phosphorus Detector

HM-S103 Handheld COD, Ammonia Nitrogen and Total Phosphorus DetectorHM-S103

HM-S103
The HM-S103 covers COD, ammonia nitrogen, and total phosphorus — the three core discharge monitoring indicators for municipal wastewater treatment — in one handheld device. At $960, it costs 54% less than purchasing three separate single-parameter units, while each parameter retains independent HJ-series standard compliance and spectrophotometric accuracy.
HM-S104 Handheld COD, Ammonia Nitrogen, Total Phosphorus and Total Nitrogen Detector

HM-S104 Handheld COD, Ammonia Nitrogen, Total Phosphorus and Total Nitrogen DetectorHM-S104

HM-S104
The HM-S104 covers COD, ammonia nitrogen, total phosphorus, and total nitrogen — the four standard discharge permit monitoring parameters — in one handheld device. At $1,100, it costs 60% less than purchasing four separate single-parameter units, while each parameter retains independent HJ-series standard compliance and spectrophotometric precision.
