  • Description


Laser Gas Analyzer LGA-4000

The LGA-4000 is comprised of a laser transmitter, receiver with electronic interface, and optional central processing unit. The transmitter and receiver are installed directly opposite one another on the process pipe / duct work. The transmitter launches a laser beam with a selected wavelength across the diameter of the pipe to the receiver unit.

The resulting electrical signal is then sent to the electronic interface or central processing unit.

TDLAS Advantages & Benefits
  • Provides immediate response to process changes
  • Eliminates sample handling cost and maintenance issues
  • Can be applied for O2, CO, CO2, CH4, NH3, HCL, and H2Ov Analysis

Eliminates cross interferences from background gases and dust, significantly improving measurement accuracy
