Outline-BM-9A

New BM-9A is small, compact, and handy Luminance meter. You can select detector units from three models, which have difference measurement angles, and you can use the BM-9A for variety purpose.
Detector unit and Main body are detachable, so the BM-9A is suited for integrating measurement systems and using in production lines.

Features

  • Handy, Low price, Multifunction

  • Detector unit can be selectable from three types and can be interchangeable

  • The BM-9A can connect to PC via USB cable. So the BM-9A used in production lines, and measurement system

  • Keyboard unit enable you to enter correction factors and conduct difference measurement

Applications

  • Measurement of luminance for LCD,PDP, OLED,LED, CCFL
  • Measurement of transmittance of Polarizing plate, films, and filters
  • Measurement of luminance in Road and Road tunnel illumination light
  • Measurement for sign illumination lights in airports and see port
  • Measurement for medical illumination and electric karte, and Schaukasten
  • Measurement of uniformity of License plate
  • Measurement for variety illumination facilities
  • Measurement of luminance of the leading block for visually handicapped
  • Measurement of reflection light from floor
