SDS3919 28.3L-0.1μm Remote Particle Counter is a dust particle counter based on the principle of single-particle laser scattering. It can accurately measure eight industry-standard particle sizes: 0.1μm, 0.15μm, 0.2μm, 0.25μm, 0.3μm, 0.5μm, 1.0μm, and 5.0μm. Through a standard RS485 interface and Modbus protocol, it transmits data in real time to various smart terminals, reducing human intervention and achieving unmanned intelligent monitoring. In various cleanroom environments, it enables continuous real-time monitoring 24/7, reducing risk and costs.
