Online turbidity sensor
productprinciple
Infrared scattering light technology, which involves a beam of light shining on a sample solution and being scattered by particles in the solution, as shown in the following figure. The angle between the emitted light from the infrared light source and the detection light is90 ° (ISO 7027). The intensity of light received by the detector is related to the turbidity of the water being measured, so the turbidity of the water being measured can be calculated by measuring the intensity of scattered light.
Product Features
(1) 90 degree infrared light scattering method, unaffected by chromaticity, widely applicable in various environments
(2) Optical and digital filtering technology eliminates the influence of stray light and ensures accurate measurement
(3) Corrosion resistant casing, waterproof rating IP68, capable of long-term underwater operation
(4) RS485 communication interface, standard ModBus protocol, easy to integrate
