Juneng - Model JNYQ-DUST-01 -Dust Monitor
High resolution, suitable for low concentration emission and high concentration emission monitoring. Single arm installation, no need for light, easy installation and maintenance. Strong anti-interference. Standard 4-20mA industrial standard current output is adopted, which is convenient for connection. The overall power consumption of the instrument is about 5W.
The collimated laser beam emitted by the laser irradiates the smoke and dust, and the scattering light of the specific solid angle generated by the smoke and dust in the measurement area converges to the detector. Through the linear relationship between the intensity of the scattering light and the concentration of the smoke and dust particles, the concentration value of the smoke and dust particles is obtained.
