The SECULIFE IM Luminance Meter is a handy, easy to use and high precision measuring instrument.
It allows the accurate measurement of the luminance in cd/m² or fL. The SECULIFE IM is ideally suited
for contact measurements with the light measuring probe placed direct on luminous or backlighted
surfaces (monitors, TV sets,light boxes, light panels). (Monitors, with the ambient light being taken into
consideration in the measurement - lighting and illumination of work stations, streets, airports,
museums, projection screens). The light sensor is color corrected, i.e. its spectral responsitivity has
been matched to the spectral photonic vision of the human eye (V λ). The accuracy class for luminance
meters has been defined in the Standard Specification DIN 5032, Part 7. The SECULIFE IM fully
complies with the requirements of Class B.Consequently all the important types of light can be
measured with high precision, without the necessity to apply additional corrrection factors. The
SECULIFE IM is provided with a data memory with 100 measurement value locations, which can be
read and processed direct with the keys and display, but also through the integrated USB Port and the
standard software provided with the instrument.
