Useful for Stress-Strain Measurements and Tensile Tests
Clip On Extensometer is a type of extensometer which provides cost effective solution for extension measurement.It includes different gauge length and strain range options to suit a wide range of specimen characteristics.Calibration certificates are supplied, showing the individual performance of each unit at its factory calibration.
These extensometers offer speed of attachment and ease-of-use. The light-weight, rugged cross-brace design eliminates errors caused by physical distortion, while built-in protection ensures that damage is not caused by over-extension. The low operating-force arms of the extensometer reduce the possibility of knife-edge slippage when testing hard or smooth surfaced materials. The extensometers can be installed or set in place accurately and consistently with rubber cord, ensuring speed and reliability of operation. These extensometers are used to measure positive strain of tensile testing.
Metal tensile testing.
Rigid plastics tensile testing.
Composites tensile testing.
To determine E modulus, n value, proof strength Rpxx, and percent elongation.
Automatic extensometer is used for automatic measurement of specimen extension during tensile tests, including axial and transverse measurement. The axial part can automatically adjust gauge length, clamp and loosen specimen, measure specimen length deformation. The transverse part can automatically clamp and loosen specimen, measure specimen width deformation. Modulus of elasticity, percentage elongation at fracture, plastic strain ratio(r) and tensile strain hardening exponent (n) of sheet metal and thin strip are determined according to the measured value.
Adopt imported grating displacement meter, resolution can reach 0.05μm.
Clamping arm can automatically clamp or loosen the specimen,saving man power and improving accuracy
Unique structure design can track the specimen deformation until fracture, but without damage to extensometer
The axial gauge length can change within 15mm-205mm automatically according to software setup.
The special design of clamping edge for axial measurement can greatly meet the sheet and bar material testing requirement.
Be able to determine plastic strain ratio(r) of sheet metal and thin strip accurately.

SreeKa's (long travel) extensometer is a precise device for measuring strain inhighly extensible materials such as elastomers, and semi-rigid plastics.The high elongation extensometer is designed to clamp directly onto to a specimen quickly and easily. It will adjust to incremental gauge lengths ranging from 10 mm or 20mm or 25mm to 800 mm.The equipment will accommodates up to 10 in of clampdisplacement and is specifically designed to permit testing the sample through rupture without damaging the extensometer or otherwise disrupting the test routine.The extensometer is based on a pair of carefully counterbalanced clamp assemblies which drive a potentiometer through connecting cables. Both clampsmove freely but any increase in the separation or differentialmotion will advance the transducer.The upper and lower specimen clamps are separately counterbalanced and guided on a polished and ground shaft with linear bearings so that none of the extensometer’sweight is applied to the specimen.
