SK2000
Hair Diameter Measurement System
The SK2000 Hair Diameter Measurement System provides an accurate understanding of the basic characteristics of a hair’s outer diameter, which can then be used as feedback for other characterization. Although various conventional methods for measuring the outer diameter of hair were available, Kato Tech chose to co-develop the SK2000 with Shiseido Company, Limited in order to provide more precise measurements more quickly.

*Operation is done via touch panel.

SK2000
Hair Diameter Measurement System
Features
Chuck feature
Both ends of the hair are held by a chuck, which allows measurement to be performed without being influenced by external forces (such as wind).
Both ends are rotated synchronously to prevent the hair from twisting.
Shape analysis
Sensors can be moved along the length of the hair, allowing for easy understanding of the hair’s shape length-wise.
Measurement of outer hair diameter
Data measurement at 360 points (1 degree per measurement point) around the hair’s circumference
2-point data measurement at the largest diameter (peak) and shortest diameter (bottom)
Automatic measurement
Automatic outer diameter measurement is possible at any point along the length of the hair and at specified intervals with an automatic feed mechanism.
Analysis method
Measurement results (data) can be sent to a PC and analyzed as Excel data.
