Durometer Testers

Asker X Durometer

Asker Hardness testers feature portable design, ease of operation, non-destructive measurement, and optional peak indicators. Supplied with 3 points NIST traceable calibration cert.

Models Available

Model F & Model FP
Exclusive type for foam materials, allowing measurement by placing the tester on the object of measurement. In addition to Model F, Model FP is available for powder puff.

Model C & Model C2
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.

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

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

Model JAL
Especially useful for recessed and/or smaller measurement areas. In addition to the standard Model JAL, long presser foot types are available for other Model applications.

Model B
It uses the same spring load used in 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.

Model JC
Model JC has 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 a higher resolution for hardness measurement of hard rubber.

Model D
Similar to Model A, this model is defined as ‘Durometer Type D’ as described in various domestic and international standards. It is in widespread use for hardness measurement of plastics and hard rubber.
