Compact, light-weight and easy to use multifunctional Illuminance Meter

The small, easy-to-use handheld illuminance meter is capable of measuring intermittent light sources, can be connected to each other to form multi-point units and is easily controlled with a PC. It has a very large measuring range of 0.01 to 299,000 lx with automatic range switching and a large, backlit LCD screen. All this with the renowned high precision level from Konica Minolta.
