BM-7 color brightness ( luminance meter, digital luminance meter ) is a lighting project, the light source and the light emitting device, film and television, traffic, building, atmospheric photometric areas commonly used test instrument.

BM-7 color luminance meter high stability, spectral response curve of Xr, rY, rZ strict matching color photoelectric detection component, embedded single chip computer system, low power band backlit LCD display, the lithium battery of high capacity, therefore, it can not only meet the laboratory use, but also is very convenient for field measurement.

BM-7 color luminance meter with a large caliber high image quality telephoto lens, the remote object or light source brightness and color of the aim point measurement. Add extension ring can be to close the small object or light source brightness and color of the aim point measurement.

(1)precision grade : 1 level (according to national metrology verification regulation of JJG554-88 )
(2) Measurement range of  luminance : 1CD / m2 ~ 120000cd / m2
(3) measurement error of  luminance : ±3% reading + 1 words (according to national metrology verification regulation of JJG211-89 verification method, index 5% higher than the allowable error requirements )
( 4) measurement range  of  temperature : 1500K - 25000K
( 5) Accuracy of color coordinates: ± 0.005 ( brightness greater than 40 CD / m2, A light conditions )
       ±0.02 ( brightness greater than 40 CD / m2, JJG554-88 transmission type colour standards conditions)
( 6)infinitely far field : measurement field of view is less than 1, more than 7 viewing field.
( 7) measuring distance: 1m ~ infinity ( plus extension ring can be measured to 0.35m)
( 9) power: battery powered or 220V AC adapter power supply
(10)observation eyepiece diopter adjustment range: - 4 ~ + 2
