What Is a Light Meter?
A light meter measures the amount of visible light, also known as illumination, in a given area. For many meter brands, including Extech, illumination is expressed in units of measure called Lux (for metric) and foot-candles (used in the US). To use an Extech light meter, the sensor is placed on a tabletop or other surface in the area to be measured and the light level reading is indicated on the meter’s display.
