A groundbreaking illuminance meter with high precision at an innovative price.
The LPPHOT02 series illuminance meter measures illuminance (lux), defined as the ratio of luminous flux (lumens) incident on a surface to unit area (m²). The spectral response curve of the photometric measurement probe approximates the human eye's response curve, known as the standard photopic curve V(λ). The difference between the LPPHOT02 series and the standard photopic curve V(λ) in spectral response is calculated as error f’₁. The LPPHOT02 series illuminance meter has a robust structure, designed for long-term outdoor use, and is primarily used for meteorological measurements in daylight.
