1、 Core definition and purpose

　　Laser ammonia escape online monitoring systemIt is a gas detection device based on laser spectroscopy technology, which can continuously monitor the escape concentration of ammonia in industrial scenes in real time. The core purpose is to prevent and control ammonia leakage, ensure environmental compliance and production safety, and widely adapt to complex industrial conditions such as high temperature and high dust.

2、 Core technical principles

Using tunable semiconductor laser absorption spectroscopy (TDLAS) technology, quantitative detection is achieved by utilizing the selective absorption characteristics of ammonia towards specific wavelength lasers.

By laser emission, transmission, absorption signal reception and analysis, ammonia concentration data can be directly output without complex preprocessing.

3、 Key performance characteristics

Fast response speed, usually in seconds, meeting real-time monitoring requirements.

Strong anti-interference ability, which can effectively avoid the influence of dust, water vapor, and other gases on the detection results.

High measurement accuracy, adaptable range as needed (commonly 0-5/10/50 ppm, etc.), in compliance with environmental emission monitoring standards.

4、 Core components of the system

Detection unit: including laser emitter, receiver, and spectrometer, responsible for signal acquisition and concentration calculation.

Sampling/optical transmission units: such as optical fibers and probes (some with blowing function), suitable for different installation scenarios.

Data processing and display unit: including host and display screen, supporting real-time data display, storage, and remote transmission.
