Features
Reflected light path is adjustable: the measurement range is from constant to trace
Adopt Single Line Spectrum technology: the measurement is free from cross interference of background gas
Adopt Wavelength Modulation Technology:with better signal-to-noise ratio and ability to resist dust and background gas interference
With low detection limit and high sensitivity; the white pool is adopted to absorb the return of optical path; optical path can reach 25cm and the detection limit can achieve 'ppm level'
With auto diagnosis to record and save fault alarm information
Modular design:simple installation and maintenance
