Product Introduction

AMT-COD300 analyzes parameters such as COD, turbidity, and temperature in water based on ultraviolet absorption method. Organic pollutants mainly produce absorption in the ultraviolet and visible bands.
Absorption, by scanning and analyzing the absorption spectrum in the 254nm UV-visible band, combined with chemical modeling algorithms, various pollutants can be qualitatively and quantitatively analyzed,
Especially suitable for judging changes in water composition or concentration. The sensor consists of a light source, spectral analysis, and measurement optical path. The light emitted by the light source is split into
Two beams. One beam is the measurement light, which undergoes spectral analysis after being absorbed by the water sample; the other beam is the reference light, which is directly subjected to spectral analysis without passing through the water sample.
By measuring the spectral characteristics of the two beams separately, the concentration of each pollutant in the water sample can be calculated

Main Application Areas

  • Wastewater Treatment — Monitoring COD levels in influent and effluent to ensure compliance with discharge standards.
  • Environmental Monitoring — Assessing water quality in rivers, lakes, and groundwater for pollution control.
  • Industrial Process Control — Real-time monitoring of organic pollutants in industrial effluents to optimize treatment processes.
  • Drinking Water Treatment — Monitoring organic contamination in source water to ensure safe drinking water production.
