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.
