ESM303 Motorized Test Stand



The ESM303 motorized test stand is configurable for tension and compression measurement applications up to 300 lbF [1.5 kN]. 

A wide range of tests can be performed, including break testing, cycling, limit testing to a load or distance, load holding, elongation testing, tensile testing, compression testing, and more.

Configurable test speed, force and distance limits, cycling, preload, and many other functions, all protected by a password. 

Individual optional functions, such as travel measurement, cycling, loadholding, etc., may be purchased either upfront or enabled in the field through an activation code. This a-la-carte platform allows for custom configuration as appropriate for the application and budget. 

Collect force and travel data, plot and analyze the results, and control test stand motion via PC-based MESUR™gauge Plus software. Or, fully control the stand by a PC through a custom-written program in any language supporting ASCII communications.


  • Selectable speed setting
  • Upper and lower travel limit switches
  • Adjustable, removal controller with intuitive menu navigation
  • Password protection of test parameters
  • Stepper motor-driven, producing smooth and quiet operation with no speed variation under load
  • USB output of force vs. time or force vs. travel
  • Compact footprint, suitable for crowded workbenches
  • Ergonomic design, with smart, clean cable management
  • Integrated electronics assembly, easily removed and transported
  • Adjustable mounting plate with T-slot base
  • 3 year warranty


  • Load capacity
    • 300 lbF (1.5 kN) @ up to 24 in/min (610 mm/min)
    • 200 lbF (1 kN) @ >24 in/min (610 mm/min)
  • Maximum travel distance: 18.0 in (457 mm)
  • Speed range:
    • Standard: 0.5 - 13 in/min (13 - 330 mm/min)
    • Optional: 0.02 - 45 in/min (0.5 - 1,100 mm/min)
  • Speed setting accuracy: ±0.2% of setting
  • Speed variation with load: ±0% (stepper motor driven)
  • Travel accuracy: ±0.002 in. per 10 in. (±0.05 mm per 250 mm)
    • Because load cell deflection and system deflection are present and not automatically compensated for, this equipment is recommended for applications requiring at least 0.2 in [5 mm] of travel distance.
  • Travel resolution: 0.001 in / 0.02 mm
  • Limit switch repeatability: 0.001 in (0.03 mm)
  • Power: Universal input 80-240 VAC, 50/60 Hz, 60W
  • Weight: 56.5 lb (25.6 kg)
  • Warranty: 3 years [see individual statement for further details]
