TRICOR's Hazer Meter and DOI is ideally suited for measuring flat, non-textured high reflectance surfaces. The Model 807A Haze Meter design is in accordance with ASTM E430 and ASTM D5767 (method A) and is used to measure ±3 degrees around the specular lobe centered at 30 degrees in approximately 220 increments. That's an angular sample size of 1 sample per 1.6 minutes of arc! This allows differentiation between samples with very small differences in reflectance characteristics. Verified replacement for the older Hunter Dorigon II haze meter unit.
