Hand-held radiometer/photometer to measure UV, visible, and IR wavelengths. The meter is provided with scotopic and photopic portable Lux detectors. The model PMA 2131 digital scotopic light sensor has a spectral response following the CIE Scotopic Luminous Efficiency Function which mimics the human eye's response in low light conditions. The model PMA2130 digital photopic light sensor has a spectral response following the CIE photopic luminous efficiency which mimics the human eye's response in the visible region. The angular response of both sensors is cosine corrected, and suitable for measurements of diffuse radiation or radiation from extended sources.
