Description

Based on tunable diode laser absorption spectroscopy (TDLAS) technology principle, iLAS-100 Laser Oxygen Gas Analyzer scans and analyzes oxygen absorption lines of 760 nm, then the concentration of oxygen can be obtained. It adopts In-situ measurement method, no need for sampling and pretreatment system, which can get an rapid and accurate measurement of oxygen in the applications of the industrial process control, flue gas emissions monitoring.

Features

  • high integration design, compact structure, simple installation and maintenance

  • no sample pretreatment needed, real-time measurement of oxygen concentration

  • single spectra scan, no interference from dust, tar and background gases

  • maintenance-free design

  • optional explosion-proof design

Applications

  • process control/explosion pre-warning monitoring

  • environmental flue gas emission monitoring

  • boiler combustion control

  • air separation and gas production

  • aerospace, electric power, electronics, biological technology and scientific research institutions, etc
