Acidic and basic gases are difficult to measure with conventional extractive analyzers because of adsorption and corrosion on the sample line. LaserGas II measures these gases by tunable diode laser absorption, directly on the duct (SP) or as a multi-pass cabinet (MP). There are separate laser modules for HF, HCl, NH3 and HCN.

Available configurations include HF SP (including a TÜV/MCERTS-approved version), HF OP, HCl SP, HCl + H2O SP (TÜV/MCERTS), HCl MP cabinet, NH3 SP, NH3 MP cabinet and HCN SP. They are used for flue gas monitoring at waste incineration, cement and chemical plants, SNCR/SCR ammonia slip control and process safety applications.

LaserGas II HF / HCl / NH3 / HCN features

  • Separate laser modules for HF, HCl, NH3 and HCN
  • In-situ measurement that eliminates adsorption and corrosion problems on the sample line
  • Combined HCl + H2O measurement option
  • TÜV/MCERTS-approved HF and HCl versions
  • Optical path 0.5–20 m (SP) or 2.7 / 11.4 m (MP)
  • 4–20 mA, RS-232, relay; optional TCP/IP and Modbus
