Computed Measurements: Combining 410 Solar & ET-100 measurement data allows the operator to manually compute solar reflectance index (SRI) in accordance with ASTM E1980

Sample Types: Flat or curved surfaces; convex and concave surfaces to have a maximum 150 & 300mm radius, respectively

Calibration: 410 Solar is supplied with standards of specular and diffuse reflectance; ET-100 is supplied a gold standard of specular reflectance

Compliance: ASTM E903 (Solar Absorptance, Reflectance, and Transmittance of Materials Using Integrating Spheres)

ASTM C1549 (Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer)

ASTM E408 (Total Normal Emittance of Surfaces Using Inspection-Meter Techniques)

ASTM E1980 (Standard Practice for Calculating Solar Reflectance Index of Horizontal and Low-Sloped Opaque Surface)

Power: Rechargeable LiMH battery; 2 hours run-time on one battery charge (1 hour recharge time)

Dimensions: 293 x 230 x 94mm (command unit with one head)

Weight: 2.13kg (command unit with one head)
