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, auto contact adapter 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.

Auto Contact
YMS motorized stands also feature auto contact which enables the durometer to align perpendicularly to the sample to make full, even contact.

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