เครื่องวัดความแข็งยางและพลาสติก Manual Durometer (CHECKLINE)

AD-300 High End Durometer
Made in Germany เป็นเครื่องทดสอบความแข็งที่ดีที่สุดที่ใช้ในการตรวจสอบความต้านทานของยางวัลคาไนซ์หรือเทอร์โมพลาสติกวัสดุยางพลาสติกอ่อนหรือพลาสติกอ่อนและผลิตภัณฑ์ซิลิกอน

AD-300 High End Durometer
Made in GermanyEasily the best available Hardness Tester to determine indentation resistance (shore) of vulcanized or thermoplastic rubbers, elastomeric or soft plastic materials and silicon products.

The AD-300 durometer fully meets the requirements of different international standards, including

- ISO 868 (A, D)
- DIN ISO 7619-1, ISO 7619-1 (A, AO, D)
- ASTM D 2240 (A, D, C, B, DO, O, OO).

This new AD-300 durometer series takes the built quality of general available durometers to the next level.
The internal friction, that is common in most durometers, is reduced to an absolute minimum.
Together with the ergonomic enlarged foot this enables you to take highly accurate repetitive measurements.

The AD-300 Hardness Tester is available in the following (Shore) versions : A, D, C, O, OO and DO
The AD-300 Durometer displays hardness readings on an easy-to-read analog scale. An optional available MEMORY POINTER holds readings until it is manually reset, allowing the operator to concentrate on measurement task.
The AD-300 Hardness Tester will be delivered with operating instructions, carrying case and calibration certificate.
