BRIGHTNESS AND COLOR TESTER-TRICOL
DESCRIPTION:
- The instrument is based on directional reflectance principle with a 0° - 45° geometry of optics.
- The pre calibration is done with primary standards like MgO or BaSO4.
- A porcelain tile is used as secondary standard for brightness measurements.
- For color matching, after calibrating with primary standard, reflectance values pertaining to the manufacturer’s standard sample are collected and stored. Further testing is done against these values.
FEATURES:
- Fully indigenous in design.
- Microprocessor based.
- Front panel digital display of Brightness, X,Y,Z color co-ordinates and L,a,b values.
- Uses three primary optical color filters for computing the Tri-Stimulus color values.
- Uses TAPPI standard for Brightness and color measurement
- Uses 0° - 45° optical geometry
- Highly useful for color control in batch processing industries
pertaining to leather, paper, textiles, paint, etc.
