The HM-2850 is ideal for applications where the operator is either not concerned with data acquisition; or, already has or is planning to construct their own data acquisition system. With its large 7" color, touchscreen, the HM-2850 provides the operator with the ability to precisely select any speed with four decimal accuracy within the machine‘s speed range. The HM-2850 features a quiet, direct drive stepper motor that provides a range of loading speeds from 0.00001 to 2.00000 in/min. This speed range is more than adequate for the majority of standard soil tests. The HM-2850 also incorporates a separate, dedicated control to accommodate 2.00 in/min. for use in Marshall and TSR Testing, as well as a rapid travel speed of 2.25 in/min for moving the platen into position quickly. Speeds are controlled through the use of edit keys and the digital display. Features Include: 8" platen provides roomy, stable base for test equipment Backlit LCD display Test speeds adjustable from 0.0001 to 2.00000 in/min. via keypad User selectable unit change between U.S. standard and metric from keypad Preset Marshall/TSR test option Load Frame includes: 3/4-16 HHG531/2 WF04— Washer
