Heavy Duty Steel Extensometer

3Rs steel extensometer is the most sturdy extensometer available on the market. It is equipped with a ball-guided mechanism completely independent from the measuring side. Its long stroke LVDT sensor allows measuring on long elongation samples. Nevertheless, the weight of the extensometer obliges its use on rigid samples (diameter over 6 mm).
