LASmini NH3
For monitoring: NH3
Laser Absorption Spectroscopy
The TRACE-GAS LASmini NH3-Analyzer combines reliability, fast response and easy handling in one instrument. Developed for a calibration-free and
direct measurement of NH3 e.g. at the SCR or SCR Sensor development.

- no formation of condensate
- selective, continuous real-time measurement
- quick response
- low detection limit
- nearly maintenance-free
- long life span
- resistant to chemicals
- long-term signal stability
- no consumables required
- Applications
- SCR development
- SCR Sensor development
