Tekpower Digital Light Level Meter LX1330B Illuminance Meter Measuring Up To 200000 Lux with High Accuracy and Rapid Response.
Digital Illuminance Meter LX1330B is a lux meter with wide measuring range and lots of nice features. A lux meter is used for checking the level of illuminance, the light falling on a surface, It is defined as: 'the density of the luminous flux incident on a surface'. It is the quotient of the luminous flux by the area of the surface when the latter is uniformly illuminated..
This convenient gadget is widely used in many areas such as construction, inspection, photography, greenhouse gardening and etc. The LX1330B can measure from 0 up to 200,000 lux, you can switch the units between lux and foot candle by simply pressing a button. It's powered by a 9V battery, which last for 200 hours or even longer. Other nice features include data hold, auto zero and more.
