SH-UVFS200 UV full spectrum absorption digital probe
Overview
The UV full spectrum absorption digital probe uses UV-Vis absorption technology to obtain the corresponding pollutant levels in water samples through dual-beam compensation combined with chemometric algorithmic analysis. The measurement system is composed by the measurement probe, the controller, the connecting cable (standard 10 meters) and the mechanical brush.
Measurement technique
Different pollutants in the water body have certain characteristics of light absorption at different wavelengths (water absorption spectral fingerprint), as shown in the following figure. Full-spectrum water quality probe detects the pollutants in the water body using 190nm ~ 750nm band absorption spectrum and chemometric mapping relationship, so as to obtain the analysis of water samples COD, TOC, BOD5, turbidity, color, TSS, nitrate, nitrite pollutant content.
