MFA20_Longitudinal_Extensometer

The extensometer MFA 20 is suitable for determining the yield point and uniform deformation for test samples above 4 mm diameter and 15 mm width. The measurement accuracy corresponds to the accuracy class 0.5 of the EN ISO 9513.
Because of its extremely robust design the instrument is suited for heavy duty service such as testing of construction steel and rough samples with scale etc.
The gauge length may be adjusted very quickly and precisely from 50 to 200 mm in 10 (5) mm-steps by shifting the lower knife edge
holder.
The clamping may be made without any problems with one hand. The parallel positioning of the MFA 20 in respect to the axis of round
samples is guaranteed by centering two double knife edges (see top view of the sketch).
