Manual Force Testers

Manual Force Tensile Testers – Hand-Crank & Manual Pull Testing Machines

Precision Tensile Testing with Manual Force Test Stands from Universal Grip Co.

Manual force tensile testers—also called hand-crank tensile testers or mechanical tensile test stands—are cost-effective, highly reliable solutions for performing tensile, compression, peel, and flexural tests on a wide range of materials.

At Universal Grip Co., we supply manual tensile testing machines engineered for ASTM, ISO, and other international standards.  Our Manual Force Testers typically ship with a precisely calibrated analog force gauge (pictured below.)  And as always all of our grips, fixtures, and adapters, whether standard or custom optimized can fit onto any Manual Force Tensile Testing Machine dependent upon your specific testing needs.

What is a Manual Force Tensile Tester?

A manual force tensile tester is a (manual) universal testing machine (UTM) operated by a manual crank, lever, or wheel, allowing the user to control crosshead movement without an electro-motor. This provides:

• High operator control for delicate specimens

• Lower equipment costs compared to motorized testers

• Portable, low-maintenance testing capability

These testers are widely used in quality control laboratories, production floors, educational environments, and field testing where portability, budget-friendliness, and precision are equally important.
