Extractive laser gas analyzer, GME700

Главная » Каталог » SICK » Анализаторы » Gas Analyzers » Extractive laser gas analyzer, GME700
 
 

High reliability and precision are the distinguishing features of the GME700 laser gas analyzer. Based on the principle of TDLS (Tunable Diode Laser Spectroscopy) and by using specific light absorption, the GME700 is able to measure several gas components, such as NH3, HF, O2 or HCl. The compact 19" unit includes the analyzer and evaluation unit as well as a heated multipath measuring cell.

At a glance

  • High selectivity due to high spectral resolution
  • No calibration required
  • No moving parts: minimal wear and tear
  • Heated multipath measuring cell
  • Hot-wet measurement

    Your benefits

  • Best application match by adapting the gas conditioning
  • High reliability during operation
  • Also applicable for harsh environment conditions
  • Easy integration into existing extractive systems
  • No problematic test gases required

    Fields of application

  • Ammonia slip measurement in DeNOx plants
  • Measurement of hydrogen fluoride in semiconductor production
  • Ammonia measurement in exhaust gas of combustion engines
  • Ammonia measurement in urea production or composting plants
  • Plastics processing
  • Hydrogen chloride monitoring in raw gas before scrubber in waste incineration plants
