MS-321LR Sky Scanner
- Daylight analysis measurement system
- Sky Irradiance and Illuminance
- 145 sequential measurements
- Auto measurement schedule
- Integrated values over full hemisphere
The automatic Sky Scanner MS-321LR is designed only to measure Luminance and Radiance of the sky hemisphere. The sensor has 2 highly sensitive detectors which respond to the low light levels of the diffuse sky and will automatically block direct radiation by the active shutter function.
The sensor with a viewing angle of 11 degrees will capture the hemisphere in 145 sequential steps. The sensor is attached to a tracker positioner with two-axis control. The MS-321LR features a precise tracking mechanism that achieves high durability and repeatability. Measurements are based on the CIE108-1994 recommendation (CIE - International Commission on Illumination, IDMP - International Daylight Measurement Program).
The luminance values are measured per kcd/m2 and radiance value per W/m2 ...
