Tdlas Technology Integrated Laser Gas Analyzer for High Corrosion
Environment
Product Description
KF series Laser Gas Analyzer developed aiming at the industrial
on-line analyzing, environmental on-line monitoring.
Many types of the KF series Laser Gas Analyzer are available,
including in-situ probe, by - pass type, multi-channel and Disc
mounted type etc.Gas types like O2,CO,NH3,CO2,CH4,H2O,HC, HF etc.
can be analyzed. The concentration analyzing of target gases
contains the macro-analysis and micro-analysis.
Features
1. Adopting the TDLAS technology, the in-situ online gas analyzing
2. Double proof probe design, without positive pressure purge, no
additional data processing unit, simple compact structure, high
reliability
3. Using high-power lasers, no fiber coupling, anti-hash working
conditions (such as excessive dust condition)
4. Using patented technology of spot light path adjustment, easy
for on-site installation

Remark1:The test conditions for 1m optical path, the gas pressure
1bar, gas temperature 300K
Remark2:By increasing the optical path, proportionally lower
detection limit
