The light data logger has a large measuring range of 0 ... 400 kLux. The illuminance is measured using an external silicon photodiode with a spectral filter. This means that the light meter can be positioned appropriately for every measuring task. The measured values can be displayed by the light meter in lux and in footcandles. In addition to the normal measured value display on the light meter, the measured value is also displayed on a scale.
