Đồng hồ đo độ cứng vật liệu mềm Asker durometer type F
Model: Durometer type F
Xuất xứ: Nhật Bản
Thông số kĩ thuật:
The ASKER Durometer Type F for much softer specimens (low hardness) gives accurate readings as it features a larger indentor and pressure foot.
The durometer exclusively for various foam materials such as urethane foam, sponge, etc.
There is no need to press the durometer into the specimen, but just to place it onto the specimen. As it is soft, the weight of the durometer constitutes the pressure to the specimen.
Indentor Height: 2.54mm Shape: Cylindrical
Pressure foot: The pressure foot in contact with a specimen is 80mm in diameter, wide enough to offer a stable measurement by placing it onto the specimen.
Our product line consists of various types of durometers applicable to specific materials as indicated in the chart above.
Type A Durometer (ASKER A type), conforming to JIS K 6235 is the most popular type of durometer for measuring rubber hardness.
However, verification is recommended because a significant difference is estimated to be the largest when a durometer indicates measurement values from 10 to 90 points.
For hard specimens for which Type A Durometer readings indicate more than 90 points, measurements should be undertaken using the Type D Durometer (ASKER D type). However, for soft specimens with measurements of less than 20 points, the ASKER C type or Type E Durometer (ASKER E type) should be used. The most important consideration in using durometers is to select the correct type for purposes of measurement according to the specimen.
