The clip-on extensometer 5025-1, 8040-1 and 7537-1
The clip-on extensometers 5025-1, 8040-1, and 7537-1 are manual clip-on extensometers that can be attached to the specimen quickly and securely with one hand. These lightweight instruments are highly accurate, yet cost efficient solutions for standard tests.
- Reproducible results are attained through the exact and lockable setting of the initial gauge length.
- Optimal gripping of round specimens with prismatic counter rollers.
- For closed loop strain rate control to ISO 6892 Method A1 and determination of the tensile modulus to ISO 527-1 Annex C.
- High accuracy in temperature chambers through compensation of temperature-related deviations.
Clip-on extensometers 5025-1, 8040-1 and 7537-1 are manual clip-on extensometers which can be clamped on to the specimen. These clip-on extensometers are heat-resistant.
In addition, clip-on extensometers 5025-1 and 8040-1 are suitable for closed-loop strain-rate control on metals to ISO 6892-1 Method A1.
Clip-on extensometers 5025-1 and 7537-1 are tailored to tests on rigid plastics and composites to ISO 527. They also satisfy the requirements of Annex C for determination of tensile modulus.
Clip-on extensometer: easy and accurate strain measurement in metals tensile test ISO 6892
The manual clip-on extensometers 5025-1 / 8040-1 are easy clipped on the specimen with one hand. Different gauge lengths, from 50 to 80 mm, can be set allowing for a variable use of the extensometers. Due to their miniaturized and lightweight construction, the clip-on extensometers can also be used for specimens with a short length.
Advantages & features
- Accuracy Class 0.5 to EN ISO 9513 up to 60% of measurement travel.
- Clip-on extensometers 5025-1 and 8040-1 are approved for closed-loop strain-rate control to ISO 6892-1 Method A1.
- Convenient one-handed operation allows fast, easy attachment and removal of the clip-on extensometer. This enables trouble-free operation, even in narrow temperature chambers.
- Cost-effective, high-precision extensometers for determination of strain on metals, rigid plastics and composites.
- Lightweight construction
- Accurate, lockable setting of initial gauge length ensures reproducible test results.
- Suitable for tensile and compression tests
