Portable flue gas analyzers

Portable flue gas analyzers

Check the compliance of your combustion installations to comply with regulations and optimize their performance by controlling the main combustion gases which are: CO-CO2-O2-NO-NO2-SO2-HC-T

Le Rasi 700

It can measure from 1 to 7 combustion gases, 6 electrochemical cells O2, CO, NO, NO2, SO2, H2S, 1 infrared cell for CO, CO2% & HC. Special cells exist for low concentrations of NO and CO (+/- 0.1 ppm).

  • The electronic unit offers a large multi-window color screen to visualize all the gases, choice of unit and storage, USB port, infrared and Bluetooth for data transfer to a PC or a printer.
  • The new filter and condensate trap are integrated and easily removable for maintenance.
  • Different sample probes are available with different length, diameter and material.


Le Rasi 800

EiUK Rasi 800, MCERTS certified, is a portable combustion and emissions analyzer capable of monitoring up to 9 gases simultaneously


  • Simultaneous measurement of O2, CO, NO, NO2, (NOx) SO2, H2S
  • NDIR non-dispersive infrared, thechnology for the direct measurement of% CO2,% CO and CxHy
  • Separate RCU remote control for wireless use
  • Integrated gas cooler and condensate drain pump
  • Wide choice of sampling probes
  • MCERTS certified

Simultaneous measurement of gases: O2, CO, NO, NO2, (NOx), SO2, H2S



Le Rasi 900-1

without doubt the most complete portable combustion / emission analyzer available on the market today. It combines non-dispersive NDIR infrared technology with electrochemical measuring cells ensuring a high level of precision, extreme flexibility and optimum performance.

The portable emissions analyzer features an integrated top gas cooler (Peltier effect cooler) and an automatic water discharge system suitable for long-term measurement and semi-continuous monitoring of emissions.

The modular heating head with replaceable heated wool filter and heated sample line provides the best conditions to prevent mold and condensate from forming during gas sampling.

Simultaneous measurement of 02, CO, NO, NO2, SO2, H2S or H2 using specially selected electrochemical cells and NDIR non-dispersive infrared technology for direct measurement of CO2% CO% or PPM and unburned hydrocarbons (CxHy) , in% or in ppm level.
