SDS3966 Liquid Imaging Particle Counter is a liquid particle counter based on dynamic image analysis principles. It can accurately measure eight custom particle sizes within the range of 15~600μm, and simultaneously output particle size and shape image information. Through a standard RS485 interface and Modbus-RTU protocol, it transmits data in real time to various smart terminals, reducing human intervention and enabling online intelligent monitoring and early warning. It can also be connected to host computer software to analyze more detailed particle size, quantity distribution, and morphological characteristics, providing data support for predictive maintenance of equipment.
