T-10A and T-10MA Illuminance Meters | Konica Minolta Sensing When you need to evaluate the illumination of light hitting a specific location or perform lux measurements, the T-10A is the illuminance meter of choice. This advanced lux meter will quickly show on the LCD screen the illumination and average values of measurements. Lux - Wikipedia The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted LM-120 Light Meter (with Auto Ranging) Data Sheet
