LY-NDUV Non-Dispersive Ultraviolet O₃ Gas Measurement Optical Modules
LY-NDUV O3 Gas Measurement Modules is based on the Non-dispersive ultraviolet O3 gas optical measurement module as the core, integrated peripheral control gas path. It is small in size and stable in performance convenient to be integrated into various O3 gas analyzers.
Pumped the Sample gas into the Modules, by alternate measurement the light intensity of the sample gas and zero gas at the characteristic absorption wavelength of O3. We can obtain the absorbance of O3 in the sample gas, the absorbance is linear with its concentration, and the O3 concentration in the sample gas is obtained through mathematical inversion calculation.
- UV-LED light source, low power consumption, Long service life, no need to preheat
- Low detection limit, high accuracy, Wide measurement range
- Built in adaptive filtering algorithm, fast response
- Without any moving parts, real-time compensation the effect of temperature and pressure, ensure the result stable and accurate under different environmental conditions
- Small volume, light weight, core weight not more than 0.9k
- The mechanical structure and specifications according to customer application requirements.
- Analysis of ozone in ambient air.
