ACCESSORIES: MINI MFA2-02-103-1 ADDITIONAL CLAMPING DEVICE For Round Samples up to 0 50 mm For Flat Samples up to 50x50 to mm MINI MFA 2 EXTENSOMETER max stroke 2 mm The extensometer MINI MFA 2 is suitable for almost all types of samples up to 0 25 mm (or 25 mm x 25 mm) and a gauge length (Le) of 100 mm. Very high resolution and accuracy allow the determination of the Young's modulus (modulus of elasticity), in addition to the yield point Rp0.2. The instrument's accuracy exceeds all requirements of the European Norm EN ISO 9513. The extensometer permits quick and easy examination of a large number of test samples. Its low weight and minimal activating force make it especially suitable for small and notch sensitive samples. The measurement range amounts to 2 mm in the positive (tensile) direction and 1 mm in the negative (compressive) direction. The large adjustment range of the clamping force allows for the optimal adaptation to the tested material and the sample dimensions. The knife edges are wear resistant and can be utilized several times over by rotating them and thus increasing their life.
