PMS6003 is a digital universal particle concentration sensor based on the principle of laser scattering. It can continuously collect and calculate the number of suspended particles with different particle sizes in the unit volume, that is, the particle concentration distribution, and then convert it into mass concentration. Interface form output. The sensor can be embedded in various instruments and environmental improvement equipment related to the concentration of suspended particulates in the air, providing it with technically accurate concentration data. PMS6003 uses the latest proprietary technology-dual laser technology, which can achieve dual laser linkage and mutual calibration, thereby extending the service life more than doubled.
