Laser extensometer
Specimen deformation can be measured in two ways:
Direct reading: the measurement is made with an extensometer measuring the deformation accurately on the specimen gage length.
The International Standards indicate if these instruments are needed or not.
Indirect reading: the measurement is made using the test machine encoder.

Description
Geovan Linear Extensometer consists of linear displacement transducer.
This Linear Extensometer is provided with two mounting blocks to install sensor to brick, concrete of rock surface.
The sensor outputs a signal proportional to the plunger travel.
Two types are available, Push & Return and Pull & Return.
0-5 Vdc signal output can be read out data logger and multimeter.

Video extensometer - RTSS
With the Videoextensometer the longitudinal and transversal strain is measured during material tests (e.g. tension, compression tests). Further analysis modules for the determination of crack length (e.g. long term tests) and crack areas (e.g. bondings) are available.
