GO1900 GONIOPHOTOMETER - GO1900

Specifications
1.Working theory of Go1900 goniophotometers
The lamps or luminaires and the photometer head are laid horizontally,and instead of the photometer head rotating around the lamps or luminaries,in this type of goniophotometer,the lamps or luminaries rotate around the photometric ceter of themselves while the photometer head is fixed.Long measuring distance can easily be achieved with this kind of goniophotometer.

2.Technical characteristics
However,no matter incandescent lamps,fluorescent lamps,metal halide lamps or some other light sources,the gravitation or the air movement would cause large fluctuation of the irradiation state of the tested light source and affect the measurement precision.Generally,this influence can achieve several percent,and even over ten percent sometimes.

3.Powerful measuring functions
Measure luminous intensity data, luminous intensity distribution,zonal luminous flux, luminaires efficiency,coefficient of utilization, luminance limitation curves, glare,maximum ratio of distance to height, equal illuminancediagrams,curves of luminaires vs lighting area, Isocandela diagrams,efficient luminescence angle etc.

4.Different data file format.
1). *.GOS EVERFINE standard
2). *.CIE CIE standard
3). *.CEN CEN standard
