Extensometer: Precision in Materials Testing

Explore the World of Extensometers

Extensometers are essential instruments used in materials testing to measure the deformation of a specimen under stress. These devices are crucial in ensuring accurate and reliable data for research and quality control in various industries. At Qualitest, we offer a comprehensive range of extensometers designed to meet diverse testing needs, ensuring precision, quality, and affordability.

Types of Extensometers

1. Clip-On Extensometers:

Clip-on extensometers are widely used due to their ease of installation and versatility. They attach directly to the specimen and are ideal for static testing applications. These extensometers are suitable for measuring strain in metals, plastics, and composites, offering high accuracy and repeatability.

2. Long Stroke Extensometers:

Long stroke extensometers are designed for materials that undergo large deformations. They are particularly useful in testing elastomers, rubber, and plastics. These extensometers provide precise measurements over extended ranges, making them indispensable in applications where significant elongation is expected.

3. Video and Non-Contact Extensometers:

Video and non-contact extensometers utilize advanced optical technologies to measure strain without physically touching the specimen. These systems are perfect for high-temperature testing, delicate materials, or situations where traditional contact methods may interfere with the test. Non-contact extensometers are ideal for dynamic testing applications and can handle complex strain measurements with high accuracy.

Applications and Uses

Extensometers are critical accessories for universal testing machines (UTMs), enhancing their capability to perform various types of materials testing. They are extensively used in:

• Tensile Testing: Measuring the elongation and ultimate tensile strength of materials.
• Compression Testing: Evaluating the compressive properties of materials.
• Flexural Testing: Assessing the flexural strength and modulus of materials.
• Fatigue Testing: Monitoring strain during cyclic loading to determine material durability.

Standards Compliance

Qualitest extensometers comply with international standards, ensuring that our devices meet the stringent requirements for materials testing:

• ASTM Standards: Our extensometers adhere to ASTM standards such as ASTM E83 for verification and classification of extensometers, ensuring high precision and reliability in strain measurement.
• ISO Standards: Compliance with ISO standards, including ISO 9513, guarantees that our extensometers deliver accurate and repeatable measurements across various testing environments.
