High temperature extensometer
Application: Hot creep and tensile test for metal materials with high E to obtain the exact length change value from the test sample
In almost all tensile testing machines in the world, the change in sample length is normally measured from the displacement of the jaws, and errors due to slipping of the jaw wedges, deformation and stiffness of the device, and non-uniform cross-section of the sample make errors in measuring the actual change in sample length. Finally, it creates the percentage of elongation and the modulus of elasticity. To eliminate this shortcoming, an extensometer is used. Changes in sample length, type of grip, accuracy and sensitivity, type of suitable extensometer are selected. The EHR-12H allows accurate measurement of sample length change in hot creep and tensile tests.

Automatic pneumatic jaw with a capacity of 25 tons
Application: Tensile jaws for metals and materials with high modulus of elasticity
During the traction test, the lateral force of the jaw must be increased to prevent the specimen from slipping or abruptly releasing. The automatic jaw provides this lateral force in proportion to the increase in tensile load. The PWG-250 automatic jaw function is pneumatic. One of the most important advantages of the PWG-250 is the increase of a constant force by pneumatic pressure to the lateral clamping force due to the effect of the automatic jaw wedge during the test. This feature prevents the sample from slipping during the test
- Automatic gripping (wedge and self-tightening in proportion to the increase in force) for sampling
- Simplicity of changing the wedges just by releasing the spring without having to open and close any screws
- Interchangeable wedges for round samples
- Pneumatic function
- Capacity: 25 tons
