SDS029-L is a multi-channel particle size sensor developed based on the principle of single-particle laser scattering. It has both particle counter and mass concentration detection functions. It can be used to measure the mass concentration of particles in the ambient atmosphere (PM0.25, PM0.35, PM0.5, PM0.7, PM1.1, PM35 , etc.). It supports up to 16 particle size channels and can monitor the mass concentration and particle size distribution (particle spectrum) of particles in real time to meet the various needs of users. Compared with traditional dust monitors, SDS029-L multi-channel particle size sensor has higher measurement accuracy and particle size resolution, and has a stronger ability to resist the influence of humidity.
SDS029-L uses industrial-grade lasers and photosensitive components, the latest generation of light scattering particle technology from Nova , carefully focused optical and gas path structures, a new generation of high-frequency weak signal processing circui
● Accurate data: single particle laser scattering principle, industrial-grade laser light source, full sampling gas analysis, high measurement accuracy, good repeatability and consistency regardless of high or low concentration;
● High resolution: the minimum diameter of the resolved particles is 0.25 microns;
● 16 particle size channels: 0.25/0.35/0.5/0.7/1.1/1.3/1.8/2.5/3.5/5/7/10/13/18/25/35 [μm], output the particle number and mass concentration of each channel;
● High reliability: aerodynamic correction, self-checking of optical and gas paths, insensitive to vibration, ensuring system reliability and stability;
● Stable flow rate: Active sampling is adopted, and the sampling component can use a constant flow air intake fan with stable flow rate. A high-performance air pump can also be used to meet the requirements of long-term long-distance high-negative pressure sampling;
● Fast response: data update within seconds;
● Easy to integrate: RS485 and UART TTL serial port output;
● Fully automatic measurement: remote control, wireless data upload, and access to the Internet of Things;
● Low maintenance: sheath gas protection structure is added to the optical part to increase the service life of the sensor in harsh environments and greatly reduce the workload of manual maintenance;
● Hose design: can be connected to external hose for easy integration;
● Safe and friendly: low voltage power supply, no electric shock; no radiation source, no light pollution.
NovaSensor SDS029-L multi-channel particle size sensor is widely used in construction sites, road dust detection, environmental big data monitoring, medicine, electronics, food processing industry, fine processing, clean rooms and other occasions that require particle concentration detection or particle size analysis.
