Specifications

	Model F Urethane Foam Sponge Non-woven Fabric Model FP Powder Puff	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 Soft Rubber Urethane Rubber Sponge Wound threads (yarn package) Rolled Films Potter's Clay (Kaolin)	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 Polystyrene Foam	This features larger indentor and a more strong spring compared to Model C, thereby making it more suitable for polystyrene foam.
	Model A Rubber in general Softer plastics	Has been used for wide applications since being standardized in the ISO.
	Rubber in general Softer plastics	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.
	Model JAL Rubber in surfaces)	Especially useful for recessed and/or smaller measurement areas. In addition to the standard Model JAL, long presser foot type are available for another Model applications.
	Model B Semi-rigid Rubber Unglazed pottery clay	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 Semi-rigid Rubber	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 higher resolution for hardness measurement of hard rubber.
	Model D Hard Rubber Plastics	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.
