CHARACTERISTICS

ASKER Model JA

A hardness tester which conforms with the Japanese Industrial Standards JIS K 6301. One of the most popular types in Japan, but has recently been gradually replaced with the ISO-specified Type A

ASKER Model JC

ASKER JC have those hardness testers described in JIS K 6301 as ‘suitable for samples found to have a hardness value above 70 according to Model A’. It features higher resolution for hardness measurement of hard ruber.

ASKER Model A

Has been used for wide applications since being standardized in the ISO.

ASKER Model B

It uses the same spring load used in ASKER Model A. It adopts a conical indentor similar to that of Model D, so as to be applicable to harder measuring objects than can be measured by Model A.

It is useful for hardness measurement of unglazed pottery clay and ceramics

in green condition.

ASKER Model C – ASKER Model C2

ASKER Model C is intended for hardness measurement of soft rubber, sponge, foamed elastomers, wound threads(yarn package), rolled films, potter’s clay(kaolin), and other such soft materials.

For even softer materials, Model C2 is available

ASKER Model CS

This features larger indentor and a more strong spring compared to ASKER C, thereby making it more suitable for poystyrene foam.

ASKER Model D

Similar to ASKER Model A, this model is defined as ‘Durometer Type D’ as descriced in various domestic and international standards.  It is in widespread

use for hardness measurement of plastics and hard rubber.

ASKER Model F – ASKER Model FP

Exclusive type for foam materials, allowing measurement by placing the tester on the object o measurement.

In addition to Model F, Model FP is available for powder puff.

ASKER Model JAL

Especially useful for recessed and/or smaller measuring areas.

In addition to the standard Mode JAL, long presser foot types are available for another Model applications.
