What is a digital light meter used for?
A digital illuminometer is an instrument dedicated to measuring illuminance. It is the degree to which the detected object is illuminated, that is, the ratio of the luminous flux obtained on the surface of the object to the illuminated area. The illuminometer is generally composed of a selenium photovoltaic cell or a silicon photovoltaic cell with a filter and a microammeter. Digital illuminance meters are mainly used in schools, hospitals, homes, offices, factories, hotels, hotels, casinos, shops, department stores and other places.
