Extensometers - a Zwick core competence

The demands placed on extensometers vary as widely as the applications for which they are used. The criteria used to determine the most suitable extensometer for a given application or range of application are also highly varied. The principal factors determining extension measurement requirements are the properties of the material to be tested, the specimen shape and dimensions
and the test standards which have to be complied with (e.g. ISO 6892, ISO 527, ISO 10113 etc.). Among other things they define the test sequence, the characteristics to be determined, and with what accuracy, and the environmental conditions, such as the test temperature.

Zwick has a comprehensive selection of extensometers, ranging from an analog clip-on instrument to the fully automatic universal extensometer. Zwick extensometers are designed with the operator in mind, so that applying them to the specimen and operating them are made as simple as possible. Our many years of experience in developing and designing extensometers, manufacturing the instruments in-house from start to finish and performing a wide variety of installations are your guarantee of state-of-the-art extensometry. Zwick’s innovations have placed the company at the cutting edge in many areas.
