Pneumatic Digital Durometer

Digital Durometer & Constant Load Stand
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
  • Includes NIST Traceable Calibration Certificate

The pneumatic digital durometer combines a constant load stand with a 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. An AC Adapter powers the pneumatic digital durometer display.

Optional SW-1 Data Acquisition Software

Use SW-1A-D4 software to capture and analyze peak and timed data from the RS-232 port. The software is a customized excel spreadsheet which displays a running log of all data. Data is automatically graphed, and the calculates max/min, mean, and standard deviation.
