The ESM303 is a highly configurable single-column force tester for tension and compression measurement applications up to 300 lbF [1.5 kN], with a rugged design suitable for laboratory and production environments. Sample setup and fine positioning are a breeze with available FollowMe™ force-based positioning - using your hand as your guide, push and pull on the force gauge or load cell to move the crosshead at a variable rate of speed.
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. Satisfy various test methods through an easy-to-use menu, allowing 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.
Force and travel data can be output to a PC for graphing and analysis using MESUR™gauge software. Or, fully control the stand by a PC through a custom-written program with ASCII communication.

Hardware and Software Options
 |
Safety shield (ESM303-003)
Provides pinch and sample debris protection for the operator. Includes an electrical interlock, preventing test stand operation while the door is open.
|
 |
Control panel tabletop mounting kit (ESM303-004)
For applications requiring remote use of the control panel. Features an adjustable viewing angle and a base with thru holes for bench mounting.
|
 |
Data collection & motion control software
Consider MESUR™gauge Plus for force vs. travel or force vs. time data acquisition, plotting, analysis, reporting, as well as motion control. The software coordinates motor start / stop and data acquisition with one click.
Note: MESUR™gauge Plus does not require any optional test stand functions, such as PC Control. If force vs. travel vs. time output is required, order the Travel Indication option. See below section for details.
|
 |
A wide range of force gauges and gripping fixtures |
 |
Interface cable, gauge to test stand (09-1214)
Connects Series 7, 5 and Series 4 force gauges to the crosshead. This single cable is used to transmit data and power. The gauge's AC adapter is not required.
|
 |
USB cable, test stand to PC (09-1158)
For force and travel data output and PC control.
|
 |
Load cell / indicator adapter (AC1062)
Accommodates any Mark-10 indicator and Series R01 or R03 force sensors. Includes mounting hardware.
|
 |
Load cell hardware kit (AC1064)
Set of hardware to adapt load cells with #10-32, 1/4-28, and 1/2-20 mounting threads.
Note that Mark-10 Series R01 and R03 load cell part numbers ending in -1 (ex: MR01-500-1) include all necessary mounting hardware for the ESM303. |
 |
Single column extensions (ESM303-001-1 / -2 / -3)
Increase the vertical clearance for tall samples. Multiple extensions may be stacked for very long samples.
Three lengths are available - 6, 12 and 24 in [150, 300, and 600 mm].
Not compatible with the ESM303-003 safety shield.
|
 |
Double column extensions (ESM303-002-1 / -2 / -3)
Accommodate up to a 20 in. [508 mm] wide sample, or ø21.5 in [ø546 mm] round sample.
Three heights are available - 6, 12 and 24 in [150, 300, and 600 mm]. Base contains rows of T-slots for fixture mounting.
Not compatible with the ESM303-003 safety shield.
