Lux8809A Professional light meter is a precision instrument used to measure illuminance in the field. It provides accurate display light level in terms of Foot Candles (FC) or LUX over wide range. It is meet CIE photopic spectral response. The meter 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. It is ideal for environmental, health and safety checks and industrial applications.

FEATURES
