Digital Extensometer / Compressometer

Digital Dial Indicator – 6 × 12 in

The Digital Extensometer / Compressometer (6 × 12 in) is a precision instrument designed to measure strain and deformation in concrete cylinders during compression testing. It is commonly used to determine the modulus of elasticity and Poisson’s ratio in laboratory and quality control environments. This testing device integrates seamlessly with concrete testing equipment for construction material analysis and research. 

How the Instrument Works

This versatile device combines compressometer and extensometer functions into a single system:

  • The compressometer measures axial (vertical) deformation during compression.
  • The extensometer measures transverse (horizontal) deformation.
  • A third center yoke attaches to the concrete specimen for diameter measurement.
  • Digital dial indicators record strain during load application.

Using both axial and transverse deformation together provides accurate data on how concrete behaves under load. For similar equipment, see the Digital Extensometer/Compressometer, Dial Indicator, 6x12in listed on Certified MTP. 

Key Features

  • Third center yoke for horizontal strain measurement
  • Digital dial indicators for precise readings
  • Simultaneous axial and transverse deformation capture
  • Lightweight aluminum yokes
  • Cadmium-plated steel components for durability
  • Designed for 6 in (152 mm) concrete cylinders
  • Complies with ASTM testing standards for concrete deformation measurement 

Standards Compliance

This instrument meets ASTM C469 / C469M standards, covering the Standard Test Method for Static Modulus of Elasticity and Poisson’s Ratio of Concrete in Compression, ensuring dependable and repeatable results in laboratories and material testing facilities. 

Why Use a Compressometer & Extensometer?

Using both measurement systems together enables engineers to:

  • Determine stress–strain relationships
  • Calculate elastic modulus
  • Evaluate Poisson’s ratio
  • Validate concrete mix performance
  • Improve structural design accuracy

These capabilities make this tool essential for labs performing concrete strength and deformation testing. 

Construction & Materials

  • Yokes: Lightweight aluminum
  • Hardware: Cadmium-plated steel
  • Indicators: Digital dial
  • Design: Easy mounting and dependable performance

This durable construction ensures reliable operation and compatibility with standard concrete cylinder testing setups. 

Typical Applications

This Digital Extensometer / Compressometer is commonly used for:

  • Concrete cylinder compression testing
  • Modulus of elasticity determination
  • Poisson’s ratio evaluation
  • Concrete mix design verification
  • Quality control and R&D laboratories

It complements other concrete test instruments such as the Compressometer/Extensometer, 6x12in for broader testing needs. 

Digital Tape Extensometer (Related Equipment)

A digital tape extensometer is another precision tool used to measure relative displacement between two fixed reference points. It is commonly used in structural monitoring and field testing.

Key Characteristics:

  • Stainless steel measuring tape
  • Portable, single-person operation
  • Relative movement measurement
  • Corrosion-resistant design

Typical Uses Include:

  • Tunnel linings
  • Caverns and shafts
  • Structural movement monitoring
  • Underground construction evaluations

Digital tape extensometers provide portable measurement support in conjunction with standard compressometers and extensometers for complete deformation analysis. 

The Digital Extensometer / Compressometer (6 × 12 in) is a durable, standards-compliant tool offering precise axial and transverse deformation measurement. Its integration with Certified MTP’s range of concrete test instruments makes it ideal for engineers, laboratories, and construction professionals seeking dependable strain data for concrete evaluation.
