Measuring Principle The low-range turbidity analyzer, through the parallel light emitted by the light source into the water sample of the sensor, the light is scattered by the particles in the water sample, and the scattered light at a 90-degree angle to the incident angle is received by the silicon photocell receiver immersed in the water sample After receiving, the turbidity value of the water sample is obtained by calculating the relationship between the 90-degree scattered light and the incident light beam.Main Features ①EPA principle 90-degree scattering method, specially used for low-range turbidity monitoring; ②The data is stable and reproducible; ③Simple cleaning and maintenance; ④Power positive and negative polarity reverse connection protection; ⑤RS485 A/B terminal wrong connection power supply protection;Typical Application On-line monitoring of turbidity in water plants before filtration, after filtration, factory water, direct drinking water systems, etc.; On-line monitoring of turbidity in various industrial production circulating cooling water, filtered water, and reclaimed water reuse systems.Specification
