Lux Meter (DT1308)

The digital illuminance meter is a precision instrument used to measure illuminance (lux, footcandle) in the field. It is meet CIE photopic spectral response. It is fully cosine corrected for the angular incidence of light. The light sensitive component used in the meter is a very stable, long-life silicon photo diode and spectral response filter.
