Pressure on the spring-loaded outer ring which exceeds the
range of the instrument by more than 100% may cause permanent
damage to the measuring spring and must be avoided under any
circumstances.
This device must not be operated in explosion hazard areas and
must not come into contact with aggressive substances.

1.0 INTRODUCTION
This manual covers the operation of both the Checkline TEXTILE and
SHORE Durometers. Textile Durometers are typically used to check the
relative "firmness" or "hardness" of textile yarn packages, bobbins, beams,
spools, cones, etc.They are calibrated to measure on an empirical scale of
0-100 units. The different models types use different sized ball sensors
(2.5, 5 and 10 mm diameter) and are offered in flat-bottomed versions (used
on large diameter cylindrical samples) as well as models with concave-shaped
bottom surfaces for use on small-diameter cylindrical test samples.
Shore Durometers are typically used to measure the hardness of a wide
variety plastics, rubber, elastomers and similar materials. All models have a
flat bottom and differ in the shape of the sensing pin as well as the internal
spring force that resists deflection of the sensing pin. All models are calibrated using standards that are specified in various Test Procedures issues by
ASTM, DIN and JIS Quality organizations worldwide.
1.1 Unpacking
Unpack the HP Durometer carefully and
inspect it for any damage. If damage is
found, contact Electromatic immediately by
telephone at 516-295-4300 or send email to
info@checkline.com.
1.2 Complete Kit
HP Series Durometers are supplied
as a complete kit, including:
• Durometer
• Operating manual
• Carrying case.
