Product Description
RK500-07 Water quality monitoring turbidity sensor
RK500-07 turbidity sensor for water quality is an instrument which uses optical principle to measure the degree of turbidity of water. This water turbidity sensor helps you monitor water quality by detecting suspended particles in various water sources, ensuring cleaner and safer water. Turbidity is caused by suspended particles in water. The suspended particles reflect the incident light. Usually, the scattered light in the direction of 90°is used as the test signal, so the unit tested is called NTU. This method is suitable for testing low to medium range, ranging from 0.01 to 4000FNU. According to EN27027 and ISO7027 standards, infrared light of 860 nm is used as light source, which cannot be disturbed by the chromaticity of samples.
