LaserGas Q is a laser analyzer family from NEO Monitors for measuring nitrogen oxides (NO and NO2) directly in line. Measurement takes place within the gas, between a transmitter and receiver mounted on either side of the duct; no sample line or conditioning is required. The optical path is typically 0.5 – 6 m, and response time is 1 – 2 seconds.

Available configurations cover NO and NO2 measuring instruments. It can be used for NOx emission monitoring and DeNOx (SCR/SNCR) control at cement, energy and waste incineration plants. Flange/purge kits and power/TU cables are supplied separately.

LaserGas Q features

  • In-situ laser measurement of NO and NO2
  • Optical path typically 0.5 – 6 m
  • Response time 1 – 2 s
  • IP66, -20 to +55 °C operating temperature
  • 3 analog outputs, TCP/IP, Modbus, 3 relays
  • Class 1 eye-safe laser, CE marked, IECEx/ATEX zone approvals
