Luminance Spotmeter Mavo-Spot 2 USB

High quality luminance spotmeter

Precision measuring instrument for the specific requirements of the professional user

The Mavo-Spot 2 USB is a precision measuring instrument for the specific requirements of the professional user with a measuring angle of 1°. The meter provides luminance measurements from the distance from 1 m to ∞, while taking into consideration the ambient light. The Mavo-Spot 2 USB is equipped with a high quality SLR optical system having a viewing field of 15° and clearly marked measuring angle of 1° in the center as well as an external focusing ring.
The accuracy classification for luminance meters is defined in DIN 5032-7, class B and in EN 13032-1, Appendix B. The Mavo-Spot 2 USB fully meets all the refulations of the class B.
A data memory for storing up to 1000 single measuring values, which can be subdivided into 10 groups, is available in the Mavo-Spot 2 USB. The memory data can be visualized and processed directly with the keyboard and the display or also in the PC via USB Port and the included standard software.

The high reliability and precision make the Mavo-Spot 2 USB ideally suitable for measuring:

- Lighting in museums, in publiv buildings and places
- Lighting of streets, roads, tunnels and airfields
- Monitors taking in consideration the ambient light
- For luminance measurement at viewing monitors in computer tomography, digital radiography, viewinng panels for X-ray films and other medical systems
- Light reflexions at work places according to the applicable Protective Laws and regulations for people at work
- Projection screens. for checking the uniformity of the illumination
