LY-NDUV Non-Dispersive Ultraviolet O₃ Gas Measurement Optical Module
The module is specially developed for NDUV O3 gas analyzers. Modular design is adopted and range can be customized, The measurement range is from ppb to % level, Small size, high measurement accuracy, easy to integrate into the O3 gas analyzer.
The module adopts the principle of non-dispersive Ultraviolet absorption and consists of a Narrow band UV LED, a gas chamber, a detector and a signal control and processing circuit. It analyzes the gas concentration by detecting the light intensity before and after gas absorption and thus calculating the absorbance.
The module adopts a new type of multi-reflection Ultraviolet gas chamber designed by Laoying, It has the advantages of customized optical path and stable optical path, achieving both high stability and low detection limit. The module has a smaller size and is convenient to be integrated into various gas analyzers.
