<br/><br/><br/><br/><br/><br/><br/> This Professional Digital Lux Meter is an accurate hand held way to <br/> check the light / exposure when taking photos. Lux Meters are also used <br/> to check the level of light in your work place meets the specified <br/> safety regulations. With this Professional Lux Meter we include a guide <br/> that shows you clearly the levels you should be meeting. Luminous <br/> intensity is measured and reported in footcandles (fc) or in lux if <br/> using metric measurement. A light meter is sometimes referred to as a <br/> lux meter. One footcandle is equal to the total intensity of light that <br/> falls on a one square foot surface that is one foot away from the point <br/> source of the light. When measuring in lux, meter is substituted for <br/> foot. This Professional Digital Lux Meter has a large LCD Screen so <br/> readings can be seen clearly, it also features the light sensor on a <br/> flex cord, so it can be positioned at will. Operation from 0 - 50,000 <br/> Lux over 3 measurements 2000, 20000 and 50000. Built in mechanics <br/> include auto zero adjustment and a low battery indicator.
