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

Product Introduction

The HM-S104 is a four-parameter handheld water quality detector covering COD, ammonia nitrogen (NH3-N), total phosphorus (TP), and total nitrogen (TN) — the four standard parameters required under industrial discharge permit compliance monitoring. Designed for facilities that must report all four values simultaneously, it replaces four separate single-parameter instruments in a single 325-gram portable device. At $1,100, the total equipment cost is approximately 60% lower than purchasing individual COD, NH3-N, TP and TN detectors. Each parameter maintains independent HJ-series standard compliance and spectrophotometric measurement precision through automatic wavelength selection and 0.001 absorbance sensitivity. The Android OS platform with 3.5-inch LCD touchscreen, 80,000+ record storage, and WiFi/Bluetooth connectivity provides a streamlined workflow from on-site sample preparation with the integrated smart digestor to data reporting.

Applications

• Discharge permit compliance monitoring — simultaneous COD, NH3-N, TP and TN reporting

• Industrial wastewater treatment plant influent and effluent quality assessment

• Municipal sewage treatment process optimization and regulatory reporting

• Pharmaceutical and chemical industry wastewater organic and nutrient load monitoring

• Petrochemical and metallurgical effluent four-parameter compliance verification

• Nutrient removal process control in biological wastewater treatment systems

Functional Performance

1. Four discharge permit parameters (COD, NH3-N, TP, TN) measured in one handheld instrument, eliminating multi-device deployment.

2. Independent HJ-series standard compliance for each parameter, ensuring regulatory acceptance of measurement results.

3. Automatic wavelength selection across parameter-specific wavelengths, no manual filter changes required.

4. 0.001 absorbance resolution with imported cold light source, delivering precise low-concentration detection.

5. Integrated smart digestor (6-chamber, PID ±0.5 °C, max 200 °C) for complete on-site sample preparation.

6. Android smart operating system with intuitive 3.5-inch color LCD touch screen interface.

7. 80,000+ record onboard data storage supporting long-term four-parameter monitoring campaigns.

8. Type-C, WiFi and Bluetooth connectivity for data export and cloud platform upload.

9. 5,600 mAh lithium battery supporting 8-hour continuous field operation across multiple sample points.

10. 325 g handheld form factor (190 × 77 × 72 mm) for true on-site portability.
