Epsilon Technology Extensometer Line

Non-Contacting

Extensometers

• Optical and laser extensometer models for non-contacting axial tension and compression
• Optical models may also be used in strain control and for cyclic testing at >100 Hz
• One system for many different tests, measuring ranges, and gauge lengths

Axial

Extensometers

• 7 models in this group cover tension, compression and cyclic testing
• Huge variety of gauge lengths and measuring ranges
• Temperatures from -270 to +200 °C (-454 to +400 °F)

High Temperature Axial

Extensometers

• 5 models cover a variety of applications for high temperature testing
• 1 un-cooled model for use inside chambers up to 700 °C (1300 °F)
• 4 models for use with split furnaces and induction heating up to 1600 °C (2900 °F)

Deflectometers

Deflection Gages

• Widely used for 3 and 4 point bending tests, compression tests and general deflection measurement
• May be used in any orientation

Transverse and Diametral

Extensometers

• 4 models cover most any test requirement and can be used with axial extensometers at the same time
• Miniature and standard units
• Extensometers for Poisson’s ratio & r-value of sheet metal
• Options for temperatures from -270 to +200 °C (-454 to +400 °F)
