Manual Tensile Testing Machines | Universal Grip Co.

Manual tensile testing machines are essential tools for precise and cost-effective materials testing across a variety of industries. Also called an analog tensile tester, these machines can provide a much more budget friendly approach to testing an application. At Universal Grip Co., we specialize in delivering dependable manual tensile testers that offer flexibility, reliability, and accuracy for quality control labs, educational institutions, and R&D facilities.

What is a Manual Tensile Testing Machine?

A manual tensile testing machine is a mechanical device used to determine the tensile strength and elongation properties of materials such as plastics, rubber, textiles, metals, and composites. Unlike motorized or fully automated systems, manual testers use hand-operated mechanisms—typically a screw or lever attached to a crank handle—to apply force to the specimen. This allows for controlled, user-driven testing without the need for expensive electronics or software systems.

Benefits of Manual Tensile Testers

  • Cost-Effective – Ideal for labs with limited budgets or low test volumes.

  • Simple Operation – No need for advanced software or programming; test results are obtained through direct mechanical input.

  • Low Maintenance – Fewer moving parts and no electronics mean reduced upkeep and downtime.

  • Portable and Compact – Many models are benchtop-sized and easily fit into small labs or classrooms.

  • Versatile Fixture Compatibility – Manual frames accept a variety of grips and fixtures for different ASTM and ISO test methods.

Applications and Industry Use

Manual tensile testers are commonly used in:

  • Educational Institutions – Teaching the fundamentals of materials testing in engineering and materials science programs.

  • Quality Control Labs – Routine batch testing for products like plastic films, adhesives, elastomers, and textiles.

  • Small Manufacturers – In-house testing without the investment of a full automated system.

  • Field Testing – Portable units for on-site evaluation of materials in construction or forensic engineering.

Common Manual Tensile Testing Standards

At Universal Grip, our manual testers are designed to accommodate fixtures and grips for a wide range of testing standards, including:

  • ASTM D412 – Rubber and elastomer tension testing

  • ASTM D638 – Plastics tensile testing

  • ASTM D882 – Thin plastic films

  • ASTM D5035 – Textiles – Strip Method

  • ASTM D3330 – Adhesive tapes – Peel test

  • ISO 37 / ISO 527 – International polymer testing standards

We offer a complete line of interchangeable grips, fixtures, and accessories to ensure your manual frame is versatile and future-proof.
