Cross Stack Laser Gas TDL Analyser - ZSS


Continuous measurement, low maintenance and long-term superior stability

ZSS Tunable Diode Laser (TDL) gas analysers provide continuous measurement of gaz concentration :

  • CO and O2 with ZSS dual beam TDL analyser (ZSS-D)
  • HCl contained in flue gas in municipal waste incineration plant and industrial waste disposal facility, NH3 in power plant and denitration equipment, CO, CO2 and O2 in iron and steel plant and chemical plants, with the ZSS single beam analyser (ZSS-S)

ZSS is installed directly on the flue pipe where target gas flow to be measured. Preparation is not required for measured gas to be introduced to the analyzer ( which is required for sampling method).
This gas analyser can be used under high dust conditions. It is possible to install upstream of the bagfilter where gas sampling is normally difficult.
