Field of application
Reliability, accuracy and very short response times are the decisive features of the GM700 laser gas analyzer. Based on the TDLAS (tunable diode laser absorption spectroscopy) principle, the GM700 measures different gas components, such as NH3, HF, HCl or 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
Device properties:
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
Benefits
In-situ measurement directly in the process for nearly uncompromised measured values
Measuring probe or cross-duct types for very good adaptation to the requirements of your measuring task
High reliability during operation
Can also be used in harsh ambient conditions
Enables the detection of quick and short-term process fluctuations

Operating Instruction (BA)
GMK03 - Gas Test Unit
The GMK03 gas test unit is used to test the linearity of the
measurement results of gas analyzers as required for a
metrological quality test (e.g. for QAL2, QAL3). For this purpose,
the GMK03 gas test unit can simulate several graded test gas
concentrations with a single (suitable) test gas.EN 01/05/2025Language:
