ATD Auto Durometer Hardness Tester

Efficient and Consistent Hardness Testing of Rubber and Plastics

Standard Features

  • Digital speed control (0.5 to 20.0 mm/second)
  • Auto Contact aligns presser foot to angled surfaces
  • Real Time, Peak and Timer Peak (dwell) modes to measure creep
  • USB Output

ATD auto durometers are designed for consistent hardness testing of rubber and plastics using constant load, speed and time controls to meet ASTM 2240 standards. The auto height adjustment and programmable clearance enable efficient test setup. Multiple scales can be tested using the appropriate durometer, contact adapter and weight.
ATD auto durometers are easily programmed using the highly visible OLED menu screens and push-buttons. Select peak, timer hold (single or dual timers) or real time mode. The Auto Average function automatically averages a selectable number of readings in peak or timer modes. Timers record the decrease in value from the peak as time elapses.
The fast approach function starts the test at maximum speed and slows to the preset measuring speed at the specified clearance. ATD also features auto contact, which enables the durometer to align to the sample in order to make full, even contact. Use USB commands to start, stop and output test results.
Hardness data can be transmitted via USB with the included cable or wirelessly. Or stored in the 400 data memory. Optional data acquisition software is available.
Optional Data Acquisition Software
SW-1-TK is a highly customized Excel spreadsheet designed to capture and analyze data from TKD digital durometers. The spreadsheet provides a running log of all measurements along with a profile and statistical information including max, min, mean, and standard deviation.
