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.
PRINCIPAL USE
- 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.
