measuring principle
- The flickering xenon lamp light source emits a full spectrum of ultraviolet to infrared light on the water sample, which penetrates the water sample through a mirror window to a diode array detector. The spectrum is accurately subdivided to 1 nm, and different light absorptions are measured. Then, based on on-site testing, experimental data, and the correlation analysis between absorption spectra and various interferences (such as chemicals, turbidity, chromaticity, etc.), advanced algorithms are used to compensate for each other, and multiple substance concentrations are analyzed.
