Brief Introduction
SJ-SGP is based on the principle that any substance has an absorption effect on specific wavelengths of light, and accurately measures the content of the substance dissolved in water by measuring the degree of absorption of these substances on specific wavelengths of light. The online full spectrum multi parameter sensor uses a xenon lamp as the light source, which can emit light of all wavelengths from near ultraviolet to near infrared. The full range of spectral information is collected through a micro fiber spectrometer. In addition, specific algorithms are used to compensate for the attenuation of the optical path and to some extent eliminate the interference of particulate suspended matter impurities, thereby achieving more stable and reliable measurements.
