[0002] Laser turbidity meter is an online water quality monitor with a microprocessor. It is an industrial online monitoring instrument designed mainly for measuring the turbidity of inlet and outlet water in municipal sewage, industrial wastewater treatment processes, water plants, etc. Its main principle is that the light waves sent by the laser sensor transmitter are absorbed, reflected and scattered by the measured object during the transmission process, and only a small part of the light can be irradiated to the receiver.

The turbidity concentration is calculated by measuring the transmittance of the transmitted light.
