It’s used for checking the level of luminance, luminance is a measure of the amount of 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. – (E = df / dA). This convenient gadget is widely used in many areas such as construction, inspection, photography and etc. Features: Precise and easy readout High accuracy in measuring LSI-circuit use provides high reliability and durability Permits a wide range of light measurements Low battery power indication Adjusting zero automatically and excellent operation LCD display provides low power consumption and clearly read out evening high ambient light Separate LIGHT SENSOR allows user take measurements at an optimum position Specifications: Color: Black + Orange (exactly as the pictures showed).
