Operating Principles

It calculates the change of particle emission concentration by reading scattered light intensity which is created by irradiating laser to the particle emissions in the exhaust gas. No need to install 2pcs of sensors and optical axis adjustment since it detects backscattered lights and a sensor has both laser irradiation part and retection part in it.
