Technical information

Measurement principle
TDLAS (laser absorption)
Measured gas
H2S
MP optical path length
2.7 or 11.4 m
Outputs
4–20 mA, 3 relays; optional TCP/IP, Modbus
Supply (MP cabinet)
100–240 VAC or 18–36 VDC
Approvals
ATEX/IECEx Ex-n options

LaserGas II H2S covers MP cabinet, SP in-situ and SP Compact versions of analyzers that measure hydrogen sulfide by laser absorption spectroscopy. No chemical sensor or tape is used; because measurement is optical, there is no sensor poisoning in corrosive and humid gases. The analyzer is also offered together with a heated probe and heated line as a complete flue gas or process gas analyzer.

Available configurations include H2S MP cabinet (standard, S-version and ATEX Ex-n), H2S SP, H2S SP Compact ATEX/IECEx Ex-n, a tail gas analysis set, an H2/H2S analysis set and an ATEX in-situ emission monitoring system that monitors H2S and flow together at a geothermal field. Sulfur recovery units, natural gas processing, geothermal plants and refinery gas lines are typical applications.

LaserGas II H2S features

  • Optical H2S measurement with no sensor required
  • MP cabinet, SP in-situ and Compact versions
  • ATEX/IECEx Ex-n and CSA options
  • Can be offered complete as a tail gas and H2/H2S analysis set
  • Can be integrated into an H2S and flow monitoring system at a geothermal field
  • 4–20 mA, relay and optional TCP/IP, Modbus outputs
