Reliability, accuracy and very short response times are the decisive features of the GM700 laser gas analyzer. Based on the TDLS (tunable diode laser spectroscopy) principle, the GM700 measures different gas components, such as NH3, HF, HCl oder H2O, by specific light absorption. In-situ measurement is particularly well-suited to the rapid determination of gas concentrations in process control and emission monitoring.
• Ammonia slip measurement in DeNOx plants
• Emission monitoring of hydrogen fluoride in aluminum smelters
• HCI measurement in combustion plants
• High selectivity due to high spectral resolution
• Short response times
• No calibration required
• No moving parts: minimal wear and tear
• No gas sampling or conditioning required
