HPG1900 goniophotometers can measure all types of lighting sources and luminaires including lamps of all kinds, indoor and outdoor luminaires, and floor lights of all kinds on C-γ plan and B-β plan, with high accuracy. IESNA files output and match international universal lighting design software, meets the requirement CIE and IESNA standard.
Characteristics and specifications:
It is design to measure luminous intensity data, luminous intensity distribution, zonal luminous flux, luminaires efficiency, luminance distribution, coefficient of utilization, luminance limitation curves, glare, maximum ration of distance to height, equal illuminance diagrams, curve of luminaires vs lighting area, isocandela diagrams, efficient lumines, center angle etc.
Rotations of test samples around both vertical and horizontal axis and rotation range:±1800
Photometer heads: CIE class A (standard class), constant-temperature, pre-amplified detector. It is a sole technology in china and superior to class 1 detector.
Adopt stable mechanical structure which means more smooth rotation and higher precise.
The rotation can be controlled by the goniometer controller or computer of high intellectual faculties and fine stability.
Accuracy of angle：0.10
Resolution of angle: 0.0010
Accuracy of photometry: CIE clad A(standard class)
Double laser alignment for position of luminaires
Compensation for the luminaires fluctuation
