Teclock Durometer Hardness Tester GS-720 Series
Durometer Hardness Tester GS-720 series – corresponding to ISO and JIS standards of rubber hardness measurement by MSP Metrology (M) Sdn Bhd from Teclock Japan
Description
For Hardness Test of Vulcanized or Thermoplastic Rubber
This is Durometer to comply with JIS K 6253 (new JIS) standard established in 1993 for the purpose of conforming to ISO (International Standard Organization). Durometrers consist of 3 types namely, Type A for medium hardness, Type D for high hardness and Type E for low hardness.
Type A tends to indicates higher value by 1~2 points compared with former Type A durometers. Type D is suitable for hard rubber having more than 90 hardness measured by type A durometer and Type E is suitable for soft rubber of which hardness is 20 and below measured by Type A durometers.
Peak Pointer Type
Some of Rubbers, Elastomer’ elastic body is not easily read the maximum value after firm contacting with a presser foot of durometer , due to the stress relaxation. The pointer indicates the descendent value but the peak pointer is holding the maximum measured value. The peak pointer type can easily read the maximum value efficiently.
In case the pointer cannot be read directly due to some obstacles altough the measuring can be done, the mesured value can be confirmed from peak pointer after measuring. The upper / lower limiters equipped will be effectively used in tolerance judgment.
Pressurized Face φ18mm Durometer mounted to Stand
Pressurized face diameter of type A and type D durometer mounted to a stand is defined 18mm by JIS standard and ISO standard. φ18mm type A(GS-719R) and type D (GS-720R) can be used as they are for measuring by pushing by hand.
