NAVPHO SDS039 online dust particle counter, also known as online particle counter, is a laser dust particle counter based on the principle of single particle laser scattering. It can accurately measure six commonly used particle sizes in the industry, including 0.3μm, 0.5μm, 1μm, 3μm, 5μm, and 10μm. Real time monitoring of particle size and number in various dust-free environments.
NAVPHO SDS039 online dust particle counter transmits real-time data to various intelligent terminals through standard RS485 interface and Modbus RTU protocol for on-site measurement and remote monitoring. Equipped with screen display, storage, and alarm functions, capable of continuous or intermittent sampling, capable of cumulative counting, and customizable communication methods.
