UV - DOAS Ultraviolet Gas Sensor ModuleKGD-YQ-538
Product Introduction
The KGD - YQ - 538 UV - DOAS Ultraviolet Gas Sensor Module adopts high - precision ultraviolet differential absorption spectroscopy gas analysis technology, which can accurately measure the gas concentrations of SO₂, NO, and NO₂. The light source is a flashing xenon lamp, which has a long service life and good stability. The gas cell is an optical path reflection gas cell, with high sensitivity and a strong absorption signal. The spectrometer uses a high - precision slit, a holographic concave grating, and a CMOS sensor, featuring a fast spectral response in the ultraviolet band, high wavelength accuracy, and good resolution, enabling gas measurement in an ultra - low range.
