Gossen Mavo-Spot 2-USB-ASM - class B - DIN 5032 Luminance meter

Gossen MAVO-SPOT 2-USB-ASM | Class B DIN 5032 high precision luminance meter

Special ASM edition includes a package of useful accessories, exclusively only available from Asmetec

The high-precision luminance meter Mavo spot2 USB for distance measurement with 1° measurement angle is classified 13032-1 Annex B and CIE 69 in Class B according to DIN 5032-7, DIN EN.

It measures the brightness effect of a surface in candelas per square meter (cd / m²) or foot lampert (Fl) in consideration of the ambient light.

The MAVO-SPOT2 USB has excellent adaptation to the spectral brightness of the human eye V (λ) and is significantly better than the requirement of the standard with the slight deviation from f1 '<3%. The measuring object can be targeted precisely in the middle above the mirror reflex optics with a 15° field of view and a sharply marked 1° measuring circuit. Distance adjustment to starting from 1 m to ∞. Shorter distances from 34 cm can be achieved via optional close-up lenses. Alternatively, a top measurement via an optional high-quality probe is possible. The velvety coating of the adapter disc prevents scratches on the self-luminous or illuminated surface.

With the comfortable one-handed operation measurement functions to be selected and starts measurements. A keystroke activates the display in the viewfinder and its backlighting.

Particularly advantageous are the comparison and ratio measurements, while the deviation of a measured value B is judged to be a reference value A and displayed. The ratio A / B is used to contrast measurement in the workplace. The percent deviation allows the assessment of the uniformity of screens or the illumination of projection screens and the difference AB is used for the control of deviations in manufacturing.
