410-Solar Handheld Reflectrometer
- AASTM Compliant
- Analysis of total reflectance
- 7 discrete bands
- Fast Calibration
- Multiple solar irradiance functions
- Immediate Data
Measure specular, diffuse and total solar reflectance
The 410-Solar Reflectometer conforms to ASTM E903 and C1549, the standard test methods for solar reflectance measurements. Measures reflectance at near-normal incidence for seven spectral bands. The 410-Solar specifies the specular and diffuse components of the total reflectance. Choose from eight solar irradiance functions, including air mass 0, 1, 1.5, and 2.0, to calculate total solar reflectance/absorptance.
