Precision
Shore Durometer
Model AD-100
The new Check-Line AD-100 analog durometer is the ideal choice for a wide range of Shore hardness
measuring applications.
The AD-100 analog durometer is the result of years of experience providing high-quality durometers to
discriminating users. Featuring an .79 inch (18 mm) footer, it offers outstanding stability and conforms
to all international standards.
The AD-100 displays hardness readings on an easy-to-read analog scale calibrated in 0 to 100 Shore units.
An optional Memory Pointer holds the reading until manually reset, allowing the operator to concentrate
on the measurement task. This feature is also valuable when using the gauge in a position where viewing
the dial is obstructed.
Seven available scales
·       A, B, C, D, DO, O, OO
AD-100 conforms  to:
·       ASTM D-2240, DIN 53505, ISO 868 and ISO 7619
·       Includes NIST-traceable calibration certificate
·       18mm diameter footer provides stable base for testing and conforms to all international standards
·       One-year warranty
·       Can be used in any measurement orientation. Gravity does not affect readings.
Specifications:
Measuring Range	0-100 units
Accuracy*	+/-1 durometer unit (A, B, C, D, O, DO +/-2 durometer units (OO)
*  Note: per ASTM D 2240-05, Sect 9.3: It is accepted that durometer readings below 20 or above 90 are not
considered reliable. It is suggested that readings in  these ranges be omitted.
