Timer Self-Cleaning COD Water Quality Sensor - AMT-COD300

Product Model: AMT-COD300

Product Introduction

AMT-COD300

Smart typeCOD sensor

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, through scanning analysisThe absorption spectrum in the 254nm UV-visible band, combined with chemical modeling algorithms, enables qualitative and quantitative analysis of various pollutants, especially suitable for determining changes in water quality composition or concentration. The sensor consists of a light source, spectral analysis, and measurement optical path. The light emitted by the source is split into two beams. One is the measurement beam, which is absorbed by the water sample and then undergoes spectral analysis; the other is the reference beam, which undergoes spectral analysis directly without passing through the water sample. By measuring the spectral characteristics of both beams separately, the concentration of each pollutant in the water sample can be calculated.
