Lateral Extensometer
Product Code : EL-CTLE-10305
Lateral Extensometer (code EL-CTLE-10305) is an instrument for measuring the lateral extension of a concrete specimen during compression testing, consisting of two movable frames, hinged together at one end, that are screwed onto the specimen. The extension is shown on a 0.002 mm × 5 mm dial gauge whose tip rests on an anvil, the zero is set with the anvil screw, and the unit is kept in a wooden carrying case.

What Is the Lateral Extensometer Used For?
When a concrete cylinder is squeezed along its axis it also widens slightly, and the ratio of that lateral strain to the axial strain is Poisson's ratio. The two hinged frames are screwed onto the specimen so that any widening opens them about their pivot and moves the gauge tip against the anvil. With the gauge zeroed through the anvil screw, the dial is read at each load step as the machine loads the specimen, and lateral strain is calculated from the readings. The standard listed for it is ASTM C 469.

Frequently Asked Questions
What does the lateral extensometer measure?
It measures the lateral extension of a specimen under test, the sideways widening that goes with axial compression, and shows it on a dial gauge.
How is the extensometer attached to the specimen?
The two movable frames, pivoted together at one end, are fixed to the specimen with tightening screws so that they follow any change in its width.
Which gauge reads the lateral extension?
Extension is read on a 0.002 mm × 5 mm dial gauge carried on the upper ring; the tip of this gauge bears on an anvil.
How is the zero reading of the extensometer set?
Before loading, the anvil screw is adjusted until the dial gauge reads zero, and readings are then taken as the load on the specimen increases.
Which standard is listed for the extensometer, and how is it packed?
ASTM C 469 is the standard listed for it, and the extensometer comes packed in a wooden carrying case for storage and transport.
