Introduction: The LD1200 is a highly sensitive and rugged design device. High-temperature extraction sampling system scheme is adopted. The high-humidity, low-concentration particulate matter in the flue duct is measured in combination with the laser forward scattering principle. It is suitable for assembling wet dust collectors and under conditions where the flue gas temperature is below zero (including droplets). Low-temperature wet smoke emission measurements. This method effectively eliminates the interference of moisture in the flue gas on the measurement of particulate matter. The principle of laser forward scattering is used, and the low-concentration measurement has high sensitivity. The core component of the LD1200 system is a light scattering sensor. The particle concentration can be accurately measured to 0.1mg/m3, the certified range is 0-15mg/m3, and the extended range can reach 100mg/m3. The forward scattering sensor uses a narrow angle forward scattering angle, thus minimizing the effects of particle type and refractive index. According to actual conditions, it can be divided into withdrawal and in-situ. Features: 1. Optical structure using laser front scattering ultra-low range, ultra-high sensitivity, the minimum detection limit 0.1/m3 2. Adopt advanced high-temperature extraction sampling and high-temperature analysis and measurement, not affected by water vapor 3. Zero point and span can be automatically calibrated, stable and reliable 4. The purge system regularly cleans the sampling line and optical inspection components, resulting in low maintenance 5. Can achieve equal-speed sampling and pre-sampling speed, can use real sampling conditions 6. Modular design for easy installation and maintenance 7. Friendly man-machine interface, large-screen menu-style easy to operate 8. Use a variety of advanced technologies. Including: correlated noise cancellation technology, laser emission power stabilization technology, extremely low noise TIA, interference control and signal integrity design, and harsh environment design technology to provide fast, reliable and accurate quantitative particulate emission data 9. Instrument design minimizes the complexity of on-site installation and many problems caused by on-site installation and commissioning.
