eLAS-300Ex Explosion-proof HF Analysis System(Positive Pressure)
The laser ammonia online monitoring system is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology, which scans and analyzes the ammonia absorption spectrum at 1512nm, and uses advanced technology such as digital lock-in amplifier and long-range gas chamber to achieve ultra-low concentration measurement of ammonia. The system selects the positive pressure explosion-proof extraction measurement method according to the requirements of the test conditions, and is simple to install and maintain, which can meet the demand for ammonia injection or fugitive ammonia detection in SCR/SNCR denitrification process.
1. Reliable long light range heating gas chamber design, light range up to 3 meters.
2. Ultra-low concentration measurement, resolution up to 0.1ppm 3. High temperature sampling, coated gas chamber, sampling loss less than 0.1ppm/m.
4. Positive pressure explosion-proof cabinet, explosion-proof sampling probe, sound and light alarm. 5. No calibration design, simple maintenance, low cost of use.
Typical applications include SCR/SNCR denitrification process control, petrochemical denitrification ammonia injection control, ammonia storage and pipeline concentration monitoring, chemical production process control and other work.
