Spectroscopic Gas Measurement Applications
-
● Consists of a ultraviolet spectrometer, an optical gas measuring cell, a ultraviolet light source and an algorithm, which have been independently designed and produced by Glit
● High resolution
● Excellent thermal and vibrating stability
● Optional spectral range
● Optional absorption length
● Easy to upgrade through modular design
● Easy to do assembly due to compact
