LONN Portable Multifunctional Digital Light Lux Meter and Illuminance Measurement Photometer Luxmeter Light Illuminometer

The Digital Illuminance Meter is a precision instrument used to measure illuminance in the field. It is fully cosine corrected for the angular incidence of light. The illuminance meter is compact, tough and easy to handle owing to its construction. The light sensitive component used in the meter is a very stable, long life silicon diode.
