SIM-3 and SIM-3Plus Spectral Irradiance Meter
The SIM-3 spectral irradiance meter brings you a fresh experience of light measurement in the mobile era. As an easy-to-use handheld device, it offers powerful functions and excellent reliability. You can accurately acquire multiple data with a single touch and easily synchronize with a PC via USB.SIM-3Plus is an updated version of SIM-3 which can achieve lower illuminance test and more accurate test result.

Measurable Quantities   

    Spectral Power Distribution P(λ)  
    Spectral Irradiance E(λ)  
    Illuminance E and Irradiance Ee  
    Chromaticity Coordinates: (x, y), (u, v), (u’, v’)  
    Color Rendering Index (CRI) and R1~R14  
    Scopic and Photopic Ratio (S/P)  
    Standard Deviation of Color Matching (SDCM)  
    Photosynthetic Photon Flux Density (PPFD): The number of photons that strikes a surface per unit time within the 400nm – 700nm wavelength range
    Photosynthetic Active Radiation (PAR): The spectral range of solar radiation from 400nm – 700nm that photosynthetic organisms are able to use for photosynthesis. It can be expressed as the energy from the radiation in this range
