LASmini NH3

For monitoring: Ammonia

LAS NH3 Analyzer

The TRACE-GAS LASmini NH3-Analyzer

based on laser absorption spectroscopy combines reliability, fast response and easy handling in one instrument. This allows the application of our LAS ammonia sensor in a wide range of fields, such as waste incineration plants, process monitoring in the semiconductor industry or SCR development. The NH3 analyzer was developed for calibration-free and direct analysis of ammonia and convinces with its selective, continuous real-time measurement.
