EXTENSOMETERS

Extensometers are compact and rugged yet light in weight. These units are widely used for testing materials such as advanced composites, metals and polymers. They can also be used to test round and flat specimens to perform tensile, compression and cyclic tests. These extensometers include circuitry for auto-calibration against internal shunt reference, thus obviating the need for on-site calibration during installation.

COD GAGES

Crack opening displacement (COD) gauges are used for fracture mechanics applications using compact tension, arc shaped and disc shaped, bend specimens or other specimen geometries in compliance with prevailing standard practices. COD gauges include circuitryfor auto-calibration against internal shunt reference, thus obviating the need for on-site calibration during installation. Knife-edges ensure firm mounting of the gauge onto the specimen without any slip and can be used up to a frequency of 25Hz.
