Precision luminance meter MAVO-SPOT 2 USB - Gossen Metrawatt

The MAVO-SPOT 2 USB from Gossen Metrawatt is a high-precision luminance meter for spot measurements with a 1° measuring angle, Class B in accordance with: DIN 5032-7, DIN EN 13032-1 (Annex B) and ISO/CIE 19476 (CIE S 023).

The instrument measures the brightness effect of illuminated or luminous surfaces in cd/m² (candela per square metre) or foot-lambert (fL) with spectral sensitivity adapted to the photopic V(λ) response of the human eye.
Its precision optical system with SLR targeting enables accurate alignment of the defined 1° measuring field, ensuring reproducible results in laboratory and field environments.

The MAVO-SPOT 2 USB from Gossen Metrawatt is suitable for professional photometric applications including contrast analysis, luminance uniformity testing and compliance verification in regulated environments.
