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:
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.
