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.
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 FollowMeTM 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 MESURTMgauge software. Or, fully control the stand by a PC through a customwritten program with ASCII communication.

Additional Features & Items
FollowMeTM Using your hand as your guide, push and pull on the load cell or force gauge to move the crosshead. Responsive enough for quick positioning as well as fine adjustments.
Force gauges Consider a Series 7 or 5 gauge for force vs. time or force vs. travel data output, and to take advantage of all available test stand functions.
Grips and eye end adapters Wide range of grips for tensile, peel, compression, and specialized applications. Eye end adapters allow for quick grip installation and removal, and prevent rotation
Indicator / load cell adapterAccommodates any Mark-10 indicator and Series R01 or R03 force sensors. Includes mounting hardware
Single column extensions Increase the vertical clearance for tall samples. Three lengths are available - 6, 12 and 24 in [150, 300, and 600 mm].
Double column extensions 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.
MESURTMgauge data collection softwareOutput force vs. time or force vs. distance data from the ESM303’s USB port. MESURTMgauge graphs, tabulates, calculates statistics, and provides reporting and output tools.
Optional Functions
Any of the below functions may be purchased at time of order or may be activated in the field at a later date via an activation code. A complete options package is also available at a discounted price. The stand is supplied in Demo Mode, a 160-hour time period in which all functions are temporarily enabled

Description
Requirements
FollowMeTM
AF008
Crosshead movement responds to manually pushing or pulling on the force gauge shaft or load cell. Increasing force produces greater speeds. Ideal for setups and quick positioning.
- Series 7 or 5 gauge or indicator with load cell - 09-1214 interface cable
Travel indication
AF009
Travel is indicated on the control unit display, with output via USB. An internal scale utilizing Renishaw technology produces significantly higher accuracy than with conventional rotary encoderbased designs. Backlash and nonlinearity are virtually eliminated
- Field hardware installation required. - If data output to a PC is required, add 09-1214 and 09-1158 cables, and a Series 7 or 5 gauge or indicator with load cell.
Computer control
AF010
The ESM303 may be fully controlled by a PC through a custom-written program in any language supporting ASCII communications. Also responds to the legacy Chatillon TCD command set and legacy Nexygen TCD software (not available from Mark-10).
- Series 7 or 5 gauge or indicator with load cell - AF009 travel indication - AF011 programmable travel set points - 09-1214 interface cable - 09-1158 USB output cable
Programmable travel limits
AF011
The stand stops at or cycles between programmable upper and lower travel distances.
- AF009 travel indication option
Overload protection
AF012
Protects a force gauge or force sensor against overload. Program the desired percentage of full scale of the gauge. Adjustable analog voltage setting allows the stand to interface with virtually any gauge with analog output
- Series 7 or 5 gauge or indicator with load cell - 09-1214 interface cable
Auto return
AF013
The crosshead moves to a limit switch, force set point, travel position, or break, then stops and reverses direction at full speed to the opposite limit.
- If reversing at force set point: Series 7 or 5 gauge or indicator with load cell, and 09-1214 interface cable - If reversing at travel limit: AF011 programmable travel limits option - If reversing at break: AF019 break detection option and 09-1214 interface cable
Cycling / dwell time
AF014
Same as auto return, but with the ability to program up to 100,000 cycles. Programmable dwell time for upper and lower limits (set independently) can be set up for up to 10,000 seconds.
- Same as auto return, at the same speed in each direction. Add AF016 for independent up and down speeds.
Independent up and down speeds
AF016
Individually configure speeds for the up and down directions.
-
Low speed range extension
AF017
Extends the standard speed range down to 0.02 in/min (0.5 mm/min).
-
High speed range extension
AF018
Extends the standard speed range up to 45 in/min (1,100 mm/min).
-
Break detection
AF019
Crosshead stops at a sudden drop in force. Programmable percentage of peak force.
- Series 7 or 5 gauge or indicator with load cell - 09-1214 interface cable
Load holding
AF020
Dynamically adjusts the crosshead position to maintain a programmed load for an indefinite or specified period of time
- Series 7 or 5 gauge or indicator with load cell - If a specified time is required, add AF014 cycling / dwell time option - 09-1214 interface cable
Preload / sample touch
AF021
Stops the crosshead and/or zeroes the travel display at an initial preload - useful in tensile, compression, spring, elongation, and other applications. Preload is programmable as a percentage of force gauge/load cell full scale. Three modes: (1) stop, (2) stop and zero, and (3) zero without stopping.
- AF009 travel indication - Series 7 or 5 gauge or indicator with load cell - 09-1214 interface cable
Profiles
AF022
Save and recall sets of test parameters, such as speeds, travel limits, preloads, etc. Up to 50 profiles may be stored.
