Extractive TDLAS gas Analyzer

LAS 300 RK

High precision measurements of selective compounds such as: HF, HCl, NH3, O2, NO, CO and H2O. Other gases on request

Ideal for applications which require reliable and specific measurements, this gas monitor is suitable for monitoring ppb and ppm concentrations in emissions, ambient
air or process monitoring. It uses rapid laser tuning and direct absorption spectroscopy to achieve very stable results

Add to Compare
  • Uses rapid laser tuning and direct absorption spectroscopy in order to achieve very low detection
  • Measurements performed at reduced pressure allowing specific measurements even in the presence of complex background gas mixtures
  • Very robust low-volume multi-pass cell. Path-length unaffected by mirror reflectivity
  • Hot / wet extractive, no sample drying or complex conditioning required
  • High sensitivity (ppb, ppm concentrations)
  • Large dynamic range
  • Interference-free gas measurements
  • Stable and repeatable measurements
  • Low maintenance
  • Reduced operation cost
  • Ultra low HCl monitoring in Emissions applications
  • High purity of gases
  • Semiconductor process
  • Traces monitoring in Ambient air (HCl / HF)
