Measure Total Solar Reflectance
The 410-Solar-i Reflectometer conforms to ASTM E903 and C1549, the standard test methods for solar reflectance measurements. Measures total reflectance at near-normal incidence for seven spectral bands. Choose from eight solar irradiance functions, including air mass 0, 1, 1.5, and 2.0.
Applications
410-Solar-i data is valuable for the following applications:
Touchscreen User Interface
The 410-Solar-i touchscreen interface provides:
- Solar irradiance function selection
- Guided calibration
- Sample labeling
- Measurement data display
