Turbidity sensor
K8500 Digital Turbidity Sensor
The K8500 turbidity sensor is based on infrared scattered light technology. Specifically, when the infrared light emitted by the light source passes through the sample to be tested during transmission, it scatters - and the intensity of this scattered light is proportional to the turbidity. The turbidity sensor is equipped with a scattered light receiver at a 90° angle, and derives the turbidity value by analyzing the intensity of this set of scattered light. Its main body is made of stainless steel, featuring a wide linear measurement range, high accuracy, and long durability.
