Digital Hand Tester +Plus Use this tester for tension or compression applications. Standard pull lengths of 12” can be increased with optional extended rods to up to 18” to test long parts. Up to 18″ range (12″ standard) Standard 11″ stroke Up to 4″ Ø platform (2″ standard) Use this tester for tension or compression applications. Standard pull lengths of 12” can be increased with optional extended rods to up to 18” to test long parts. It has higher resolution force and length to test with greater accuracy. Includes Length Deflection Compensation What is length deflection compensation? All force/lengh testing devices, regardless of manufacturer, have additional deflection by the load cell and tester frame which occurs as the spring is loaded. If you buy/use a tester without deflection compensation, measurements might include significant length errors. Spring deflection, also known as spring travel or motion, is the action of a compression spring compressing (being pushed), an extension spring extending (being pulled), or a torsion spring winding (being twisted) when a load is applied or released. This is one characteristic (spring deflection) that is measured by a Larson Systems Spring Tester. Larson Systems has BUILT-IN Length Deflection Compensation so that the user does not have to calculate and apply length corrections. Most competitors do not have length deflection compensation. With a Larson Systems product, forget about calculating load cell and frame deflection when testing, we’ve got you covered.
