The Check-Line AD-300 precision durmometer 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 calibration certificate.
