LaserGas II MP (Multi Pass) is a multi-pass TDLAS analyzer housed in a cabinet, used when low concentrations must be measured. A mirror system lets laser light travel an optical path of 2.7 or 11.4 m inside the sample cell, so ppm-level components can be measured in a short cell volume. The sample is brought to the cell through an extractive line.

MP configurations include O2, CO, CO2, CH4 (at ppm and % level, including CH4 in hydrogen) and H2 cabinets. ATEX Zone 2 Ex-n cabinet options can also be offered with a heated probe and heated line as a complete flue gas analysis system. Extractive furnace oxygen analysis systems are among the typical applications of this family.

LaserGas II MP features

  • Multi-pass optics: 2.7 or 11.4 m optical path
  • Response time shorter than 20 seconds (dependent on sample flow)
  • Repeatability: 1% of measurement range
  • 1–3 pcs 4–20 mA outputs, 3 relays (high gas, maintenance/warning, fault)
  • Optional TCP/IP, Modbus and fiber optic communication
  • 100–240 VAC or 18–36 VDC supply
  • ATEX/IECEx-approved Ex-n cabinet options
