Technology Used

The following instrument configurations are available in the Laser product line:
- The LaserSP monitors are mainly used for in-situ measurements across pipes, stacks, ducts with path lengths of 0.5 to 20m.
- The LaserCompact monitors are optimised for short distance measurement across pipes and extractive measurement cells with a path length of the range 0.1 to1m with low purge gas consumption option.
- The extractive LaserExact monitor multipass cell provides ppb or low ppm detection limits.

 

Features

  • The range includes models for measuring O2, HCl, HF, NH3, CO, CO2, H2O, H2S, HCN, CH4 and other hydrocarbons, as well as for measuring two different gases or a gas and temperature simultaneously using a single laser.
  • Robust instruments suitable for harsh and hazardous environment

Typical Applications

  • Emission control systems for scrubber and abatement plants.
  • Combustion control systems for boilers and waste incinerators.
  • Ammonia slippage control in deNOx plants.
  • Safety systems in chemical plants.
  • Trace measurements in pure gases.
  • Moisture measurement in natural gas.
