Product Introduction
7034(12mm).png "Multi-angle color & effect control")
Total color impression of effect finishes
The appearance of effect finishes is influenced by different viewing angles and viewing conditions. Apart from a light-dark flop and color shift special sparkling effects can be created. The BYK-mac i spectrophotometer is unique as it measures both multi-angle color and flake characterization in one portable
device.
■ Traditional 5-angle color measurement: 15° / 25° / 45° / 75° / 110°
■ Additional color measurement behind the gloss for color
travel of interference pigments: -15°
■ Sparkle and graininess measurement for flake
characterization
Ergonomic design and easy operation
The shape of the instrument is designed to ensure easy handling and true portability. Due to its intuitive menu quality control of metallic finishes has never been easier.
■ Menu guided operation according to your own sampling procedure
■ Designated buttons for standard and sample readings
■ Scroll wheel to select menu functions
■ Large color display – easy-to-read inside and outside
■ Storage of up to 1000 readings in selectable memories
■ smart-chart software for professional analysis, documentation and data management.
Reliable readings at any time
In order to guarantee stable positioning, the BYK-mac i is
equipped with trigger pins on the bottom plate of the instrument.
If the pins do not have contact with the surface, an error message
will be displayed. This ensures reproducible results on test panels
as well as curved parts (r > 500 mm).
Additionally, the surface temperature is measured and saved with
each measurement.
Accurate results and low maintenance
The BYK-mac i spectrophotometer uses a light source with longterm stability and patented illumination control which provides superior accuracy and low maintenance for many years.
■ Stable, long-term calibration – needed only every three months
■ Temperature independent measurement results between 10 – 40 °C – without calibration
■ Excellent agreement between instruments allowing usage of digital standards among the supply chain
■ 10 year warranty on the light source – no lamp changes needed
Always ready
The instrument is operated with a rechargeable battery pack (Li-Ion). The docking station automatically charges the battery pack in the instrument as well as a spare pack located in the docking station. Optionally the instrument can be operated with 4 standard mignon alkaline or rechargeable batteries. The docking station also transfers measured data to a PC.
Quantification of Fluorescent Light
The BYK-mac i spectrophotometer is equipped with additional sensors to detect fluorescent light excited in the visible range. The Intensity Emission value quantifies the fluorescent light and can be used as a preliminary indicator for light fastness.
