SDS029-FQ multi-channel particle spectrum sensor Introduction: SDS029 is a multi-channel particle spectrum sensor developed based on the principle of single particle laser scattering, which combines particle counter and mass concentration detection functions. It can be used to measure the mass concentration of particles (PM0.3, PM1, PM2.5, PM4, PM10, TSP, etc.) in the ambient atmosphere. It supports up to 31 particle size channels and can monitor the mass concentration and particle size distribution (particle spectrum) of particles in real time, meeting various usage needs. Compared to traditional dust meters, SDS029 has higher measurement accuracy and particle size resolution, as well as stronger resistance to humidity effects. characteristic: 31 channel particle size output: can simultaneously output mass concentration and particle number (0.25pm, 0.3pm, 0.35 μ m, 0.4 μ m, 0.5 μ m, 0.6 μ m, 0.7 μ m, 0.8pm, 1pm, 1.1pm, 1.3 μ m, 1.6 μ m, 1.8pm, 2.1 μ m, 2.5 μ m, 3 μ m, 3.5 μ m, 4pm, 5 μ m, 6 μ m, 7 μ m, 8 μ m, 10 μ m, 11 μ m, 13 μ m, 16 μ m, 18 μ m, 22 μ m, 25 μ m, 30 μ m, 35 μ m) 2. There are two types of sampling: air pump and fan. Different sampling methods can be selected, with a flow rate of 1-4L/min to meet more needs 3. Reliable operation: all industrial grade devices, professional optical solutions, high accuracy, and long service life 4.
