Our range basically includes two models: clip-on and coaxial extensometers.
Clip-on extensometers (available in a mechanical and an electronic version) are useful to detect strain during the first stage of the test (up to yield phase) and must be removed from the specimen before the rebar failure.
Electronic coaxial extensometers are applied directly to the specimen and remain connected until failure, measuring specimen extension with high precision during both the elastic and plastic stages.

Introduction
Extensometers used for measuring the extension of specimens in traction, particularly in the case of steel and brittle materials, are only able to detect strain during the first stage of the test, or rather, while the brittle materials conserve their elasticity as they have to be disconnected before failure. This simple and economic system fully satisfy these requirements because:
Description
The extensometers are basically made by 2 clamping devices and a middle tubolar steel part determining the gauge length of 200 mm.
| Models | 70-C0961/G | 70-C0961/H | 70-C0961/E |
| Measuring range dia. Min/Max | 16 – 40 | 6 – 26 | 6.35 – 15.2 (strands) |
| Base length | 200 mm | 200 mm | 600 mm |
| Transducer travel | 75 mm | 50 mm | 50 mm |
Used to measure the elongation of steel rebars, round and wire steel specimens.
Standards ASTM A370 EN ISO 15630-1
Used to measure the elongation of steel re-bars, round and wire steel specimens.
Both models feature a base of measurement from 50 to 200 mm. They have to be removed before sample failure. Supplied in a carrying case.
