Finding F-0265

“The calibration models adjusted for particle CRI and density account for non-linearity in the OEM’s mass concentrations estimates with NMAE within 5.0%.”

Huang et al. Assessing the value of complex refractive index and particle density for calibration of low-cost particle matter sensor for size-resolved particle count and PM2.5 measurements (2021). PloS one. Page 1. CKB 8344

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Method: Low-cost sensors
Setting: laboratory, US
Study design: laboratory calibration study of a low-cost optical particle sensor (Plantower PMS) against an aerodynamic particle sizer with test aerosols of known complex refractive index and density (class 4)
Effect: other 5.0
Caveat: printed as NMAE within 5.0 %
