  • AQMS-900C-PM?.? Particulate matter monitor

    AQMS-900C-PM?.? particle monitor uses the principle of beta ray absorption to monitor the concentration of fine particulate matter PM?.? in the air. The system configuration includes a cutting head, filter membrane, and calibration membrane. Beta rays are a high-speed electron stream. When it passes through particulate matter, part of the energy is absorbed by the particulate matter, causing the intensity to attenuate. The attenuation of low-energy beta rays is only related to the mass of the absorbing material and has nothing to do with other physical properties (such as particle dispersion, color, gloss, shape, etc.). Therefore, by measuring the attenuation of beta rays, the amount of air in the atmosphere can be calculated. The mass concentration of particulate matter.

  • T1100 UV fluorescence sulfur dioxide analyzer

    The T1100 sulfur dioxide (SO?) analyzer uses ultraviolet fluorescence method to analyze SO? in ambient air. Under the irradiation of a Zn lamp (214nm), the SO? molecules receive ultraviolet energy and become excited states. When the excited SO? molecules return to the ground state, they emit characteristic fluorescence. The fluorescence intensity signal is converted into an electrical signal by a photomultiplier tube, which is then micro-processed. processor to generate SO? detection concentration data. It meets the application requirements for online monitoring of ambient air and online monitoring of pollution sources by dilution method.

  • T1200 Chemiluminescence nitrogen oxide analyzer

    The T1200 nitrogen oxide (NOx) analyzer uses chemiluminescence method to analyze NOx in ambient air. Nitric oxide (NO) reacts with ozone (O?) to generate excited state nitrogen dioxide (NO?). When the excited state NO? returns to the ground state, it releases luminescence energy with a wavelength of 600nm to 1200nm. The photon energy released is detected and the laser is used. Berber\'s law is used to find the concentration of NO?, and the original NO? in the air is found through the difference between NOx and NO. This equipment is used for online monitoring of ambient air and online monitoring of pollution sources by dilution method.
