H&D 3000 Automated Hardness and Density Tester

The H&D 3000 automated rubber hardness and density tester is designed for high production laboratories requiring regular intervals of both physical properties. MonTech robotics systems carefully handle the sample through each step, measuring each sample until the test completed. Test sequences are easily programmable and modifiable. Due to the unique rotary tray design, the instrument can be continuously loaded and operated. Once the data is collected through MonDevice software, data may be processed into database host systems.


  • Fully automated hardness and density measurement
  • Programmable test sequences
  • 60 different data points with pass/fail evaluation
  • Continuously loaded rotary tray
  • Precise sample handling and removal
  • Integrated pump circuits
  • Hydrostatic weighing
  • Additional hardness testing heads: Shore A, B, C, D, DO, O, OO, OOO, Micro A, Micro D, IRHD N, M, L, VLRH
  • Optional barcode scanner for compound and batch identification
