The Checkline Europe AD-100 analog durometer is the genesis of years of experience offering high quality durometers to discriminating users.
Featuring an 18 mm footer that offers high stability and conforms to all international standards, the AD-100 is the ideal durometer for a wide range of shore hardness measuring applications.
5 models are available each calibrated for a different Shore scale including;
The AD-100 displays hardness readings on an easy-to-read analog scale calibrated in 0 to 100 Shore units. An optional MEMORY POINTER (not suitable for shore OO and OOO) holds reading until manually reset, allowing operators to concentrate on measurement tasks. Also valuable if used in a position where the dial is obstructed.
All AD-100 models are supplied in a foam-fitted protective carrying case along with NIST traceable calibration certificate.
