Dial Gauge Compressometer / Extensometer – 6 in
Accurate Concrete Strain & Modulus Testing
The Dial Gauge Compressometer/Extensometer (6 in) is a precision instrument used in Concrete Testing Equipment to measure strain during compression testing. It helps determine key mechanical properties such as modulus of elasticity and Poisson’s ratio.
This device measures both axial deformation and horizontal extension of concrete cylinders at the same time. It is widely used in material testing laboratories, quality control facilities, and research environments.
How It Works
- A compressometer measures vertical strain during loading
- An extensometer measures transverse (horizontal) deformation
- A third center yoke attaches to the specimen to capture lateral movement
- Mechanical dial indicators record deformation in real time
Using both measurements together provides a complete understanding of concrete behavior during compression testing of concrete cylinders.
Key Features
- Designed for 6 in (152 mm) concrete cylinders
- Third yoke for horizontal extension measurement
- Dual mechanical dial indicators for axial and transverse strain
