DTU-900-OA3

It is used to measure the yield point and elongation of metals and nonmetals, and is specifically designed to be suitable for samples with long elongation.

Typical strain gauge types of elongation meters are more precise, but it is difficult to measure samples with a elongation of more than 200% to the break point.

Rotary encoder-type extensometer can be applied to samples with relatively low precision but which has elongation higher than 1000%. 

What is important in this kind of elongation meter is whether it can follow the sample well without slippage until the end during the tensile test.

Daekyung Tech minimizes this concern by providing knifes of various designs depending on the shape, material, and elongation of the sample.

It is equipped with a multi-position guide that allows you to easily and quickly match the viewing distance, adding to the convenience of use
