2010-06-01: Wolf Willborn testers improved
The Wolf Willborn tester has been redesigned. The changes include the replacement of ball- by slide bearings, which result in a smoother movement.
The former pencil set is replaced by the new Koh-i-noor 1500 pencil set, which consists of 20 pencils in an aluminum case. The ISO 15184 standard refers to this Koh-i-noor 1500 pencil set.
The new set of pencils is standard supplied with the single and the dual weight Wolff Wilborn version. Just like the other TQC equipment a calibration certificate is part of the standard supply as well.
