EASYVIEW BIG DIGIT, WIDE RANGE LIGHT METER The EA30 measures up to 40,000 foot-candles in four ranges and 400,000 lux in five ranges with ±3 percent accuracy, making it ideal for outdoor use. This light meter features a compact and rugged design with a large display and analog bargraph to view trends. Comes with built-in stand, remote sensor with protective cover and 39-inch (1-meter) coiled cable, protective rubber holster, six AAA batteries, carrying case, and user manual. Model EA30-NIST is also available with a NIST traceable Certificate of Calibration.

Also has data hold, min/max, and auto power off functions. 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.
