This system employs TDLAS technology for in-situ online monitoring of ammonia in industrial denitrification flues. It features high ivity, dust resistance, precision, and rapid response. Core technologies include: precise concentration inversion using specific wavelength lasers; spectral scanning to eliminate dust and window contamination effects; separate host and sensor unit installation (up to 1,000m apart); built-in calibration cells for maintenance-free, driftfree operation; support multi-point monitoring; and wide detection range (ppm to % levels).
