The Check-Line AD-300 precision durometer is designed to measure the hardness of vulcanized or thermoplastic rubbers, elastomeric or soft plastic materials and silicon products via indentation resistance.
The AD-300 durometer meets the requirements of most international standards, including:
- DIN 53505 (A, D)
- ISO 868 (A, D)
- ISO 7619 (A, AO, D)
- ASTM D 2240 (A, D, C, O)
The AD-300 is German-engineering with the highest build employing an ultra-low friction movement and an indentor machined to the highest standards. Together with the ergonomic enlarged foot this enables you to take highly accurate and repeatable measurements.
The AD-300 Hardness Tester is available in Shore A, D, C and O scales
Hardness readings are displayed on an easy-to-read analog scale. An optional MEMORY POINTER holds readings until manually reset, allowing the operator to concentrate on the measurement task. The AD-300 Hardness Tester will be delivered with operating instructions, carrying case and manufacturer's certificate. A full calibration certificate can be ordered optionally.
- Ergonomic barrel and 18mm footer offers stable platform for measurement eliminating "wobble"
- Large easy to read dial indicator (0-100 units)
- Memory pointer optionally available
- Highly accurate and repeatable
- German-engineered and built
- Conforms to DIN 53505, ISO 868, ISO 7619 and ASTM D 2240
- Traceable calibration certificate Optional
