807 DOI and Haze Meter

Model 807 Haze Meter and DOI, replacement for Hunter Dorigon
  • Can be customized to measure your product’s appearance characteristics
  • Measuring flat, non-textured high reflectance surfaces
  • ASTM E430 and ASTM D5767 (method A)

Replacement for the obsolete Dorigon II

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.

Operators need only press 1 button on the unit to obtain a measurement in less than 4 seconds. Computed results include Rs (specular gloss), DOI (Distinctness-of-image gloss) and haze (2 & 15 degrees). The device can help quantify reflectance, doi, haze, sheen, reflection directionality, reflectance haze, metallic brightness for metals, glass, ceramics, painted surfaces and any other high reflectance surface. The system was designed as a direct replacement of the obsolete Dorigon II.

The system is operated via RS232 from any PC (w/Windows™) or Palm Personal Digital Assistant. Quickly switch from a mirror standard to a black glass standard for non-metallic measurements. Statistical sample averaging is performed. Each measurement is time and date stamped. Data can quickly be downloaded directly into a MS Excel spreadsheet.

Low power consumption and power saving features allows standard AA NiCd type batteries to be used. Battery life is in excess of 10 hours of continuous operation without need for new batteries. An optional ac adapter and battery charger is available for use with rechargeable batteries. A Non-contact optional configuration is also available.

The Model 807A Haze Meter can be configured for either contact or non contact measurements. The non contact configuration allows easy integration into a production line.
