DD-300 Digital Precision Durometer
DD-300 Digital Precision Durometer SPEC
Product Information 
DD-300 Digital Precision Durometer
Made In Germany
Application:
Our new DD-300 Durometer range takes rubber / plastic hardness testing to the next level.
This DD-300 hardness tester has been designed to have almost no internal friction and therefore meets the highest quality standards.
The entire internal movement is guided by bearings and makes this one of the best digital durometers available today.
The DD-300 Durometer is available in Shore A, C, D, O, OO, AO, DO and Asker C.
Features:
- Highly accurate and repetitive
- Measuring Modes:
- Continuous Mode
- Peak Mode
- Timer Mode
- Timer function to take measurement after (0-15) seconds.
- Conform to DIN ISO 7619-1, ISO 868, ISO 7619-1 and ASTM D 2240
- No internal friction due to precision engineered bearing system for internally moving parts.
