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.

Product Features

• Adopting UV - DOAS technology, it can simultaneously measure SO₂, NO, and NO₂ components with high measurement accuracy.
• Through the combination of different optical path gas cell specifications, it can achieve measurements of ultra - low and high - range concentrations.
• The detection range of SO₂ and NO is as low as 50mg/m³, meeting the requirements of ultra - low emission detection.
• Modular platform with a compact structure, equipped with air pump and solenoid valve control interfaces, facilitating integration.
