Features & Description
  • CAPACITY: 300 lbf /150 kgf /1500 N

Made in America, the ESM303 is a highly configurable single, or double column motorized test stand for tension and compression measurement applications up to 300 lbf [1.5 kN].

Force Data is displayed by a wide selection of digital force gages, providing USB data output, overload protection and force set points.

The ESM303 can be purchased in its basic form with your selection of any of the Controller Options or, can be purchased complete with all Controller options.  The Basic ESM303 is supplied in Demo Mode, a 160-hour time period in which all optional controller functions are temporarily enabled.  All optional controller functions are contained in the Basic ESM303 controller and can be activated later by paying for the required option and activating it with the option’s code from Mark-10.

With generous travel, clearance, and depth dimensions, a wide range of tests can be performed, including break testing, cycling, limit testing to a load or distance, loadholding, elongation testing, tensile testing, compression testing, and more. The user-friendly menu on the removable controller allows the configuration of test speed, force and distance limits, cycling, preload, and many other functions, all protected by a password. Save up to 50 profiles to accommodate a range of test methods.

When the ESM303’s clearance is insufficient for the application, its modular mechanical design allows for single and double-column extensions. Modularity extends to the controller functions as well. Individual 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.
