Features
1. The reflectance range is adjustable and the measurement range covers constant to trace
2. Single-line spectroscopy is used to measure with cross-interference from background gas
3. Using wavelength modulation technology, with better signal to noise ratio indicators and anti-dust, background gas interference
4. Low detection limit, high sensitivity, the use of white pool is to absorb the reflective optical path. The optical path up to 25 meters can achieve detection limit of ppm level
5. With automatic diagnostic function, record and save abnormal alarm information
6. Modular design, easy for installation and maintenance
