Smart Transmitter

GALGT-1 is a kind of panel-mounted tunable laser gas Analyzer, which is developed for industrial online analysis and environmental online monitoring. The Analyzer adopts white pool to realize the return of optical path. The optical path can reach 25m and the detection limit is low. It can online analyze O2, CO, NH3, CO2, CH4, H2O, HCl, HF, HCN and other gases under various complex working conditions (Note: a single Analyzer can only analyze 1~2 components). The measured gas concentration ranges from constant to trace.

  • 19-inch 3U panel mounted chassis, compact structure and easy integration
  • TDLAS technology is adopted to eliminate cross interference of background gas
  • Multiple Reflection Optical Path technology: the measurement optical path can reach up to 25m, significantly improving the detection limit
  • No optical moving parts, high reliability, free from field vibration
