HM-S102 Handheld COD and Ammonia Nitrogen Detector

Product Introduction

The HM-S102 is a dual-parameter handheld water quality detector integrating Chemical Oxygen Demand (COD) and Ammonia Nitrogen (NH3-N) measurement in one compact device. These two parameters represent the most commonly monitored combination for wastewater discharge permit compliance — covering organic pollution load and nutrient pollution simultaneously. The instrument employs spectrophotometric detection with an imported cold light source, automatic wavelength selection, and 0.001 absorbance sensitivity for both parameters. COD measurement complies with HJ/T399-2007 across four ranges from 10 to 15,000 mg/L, while ammonia nitrogen follows HJ535-2009 from 0.05 to 200 mg/L. At $810, the HM-S102 costs 37% less than purchasing a standalone HM-SCOD ($660) and HM-SNH-2 separately, making it the cost-efficient choice for facilities that routinely monitor both discharge indicators.

Applications

• Wastewater discharge permit compliance monitoring — COD and NH3-N dual-parameter reporting

• Municipal sewage treatment plant influent and effluent quality assessment

• Food and beverage processing wastewater organic and nutrient pollution control

• Pharmaceutical industry effluent COD and ammonia nitrogen regulatory testing

• Paper and pulp mill wastewater dual-parameter discharge monitoring

• Industrial park centralized wastewater treatment facility routine compliance checking

Functional Performance

1. Dual-parameter integration — COD and NH3-N measured in one handheld device, eliminating the need for separate instruments.

2. COD four-range coverage (10–150, 20–450, 50–1,500, 500–15,000 mg/L) per HJ/T399-2007, from low-concentration surface water to high-load industrial effluent.

3. Ammonia nitrogen four-range coverage (0.05–7.5, 0.2–15, 2–50, 4–200 mg/L) per HJ535-2009, suitable for most wastewater and surface water monitoring scenarios.

4. 37% cost savings over purchasing separate HM-SCOD and HM-SNH-2 units while maintaining equivalent spectrophotometric accuracy for each parameter.

5. Automatic wavelength selection — the instrument switches between COD and NH3-N measurement wavelengths without manual filter changes.

6. Android smart operating system with 3.5-inch color LCD touch screen for intuitive dual-parameter workflow management.

7. Imported cold light source with stable optical output and up to 100,000 hours lifespan.

8. Digestion-colorimetric integrated tube design simplifies sample preparation for both COD and ammonia nitrogen testing.

9. 80,000+ record onboard data storage supporting long-term dual-parameter compliance tracking.

10. Type-C, WiFi, and Bluetooth connectivity for cloud platform data upload and remote compliance reporting.

11. 5,600 mAh lithium battery providing 8-hour continuous field operation across both test parameters.
