YMS motorized durometers are designed for consistent hardness testing of rubber and plastics using constant load, speed and time controls to meet ASTM D2240 standards. Auto height adjustment makes for quick setups. Multiple scales can be tested using the appropriate durometer and weight.


YMS motorized stands are easily programmed using push-buttons and highly visible OLED menu screens. Selectable Auto or Manual modes with timer hold and digital speed control up to 20mm/sec. Fast Approach
starts tests at maximum speed combined with selectable clearance, which slows movement to the preset measuring speed to avoid overshoot.

External Control

Use ASCII commands to start, stop or output results. Or use the open collector contact signal to start and stop.

Optional Auto Contact Adapter

Optional Auto Contact adapter automatically aligns the durometer foot parallel to the sample surface to comply with ASTM D2240 requirements, eliminating the need for user verification before testing.
