Pneumatic Digital Hardness Tester

For Plastic & Rubber
D4M-A (Shore A Scale)
D4M-D (Shore D Scale)
D4M-C (Asker C Scale)

Standard Features

  • Pneumatic, adjustable speed control for consistent speed
  • Proprietary flexible coupling aligns presser foot to angled surfaces
  • Real Time, Peak and Timer Peak (dwell) modes to measure creep
  • RS-232 Output

The digital hardness tester for rubber and plastic combines heavy-duty metal construction for stability, standard weights for constant load and adjustable pneumatic speed to maximize consistent results. Additionally, the unique flexible coupling enables the presser foot of the durometer to make perfect contact on flat or angled surfaces.
Measure vulcanized and thermoplastic rubber hardness in Shore A, D and Asker C scales in peak, real time or peak with timer modes with a minimum reading of 0.1 point. The timer (dwell) function offers push button selection of DIN/ISO, JIS and ASTM standard intervals and a user-defined interval (0-99 seconds). Collect peak data from the RS-232 port. Powered by an AC adapter.

Optional SW-1 Data Acquisition Software

Use SW-1 software to capture and analyze peak and timed data from the RS-232 port. A running log of all the data is displayed along with a chart. Calculates max/min, average, and standard deviation.
