20KN Two Columns Metal Tensile Strength Machine With Accurate
Extensometer
1.introduction
20KN two columns metal tensile strength universal testing machine
with accurate extensometer mainly Matches with various test
fixture, like peal, puncture, tear, pneumatic grip, belt tension,
etc. This UTM can be used to metal, non-metal, composite materials
like rubber, steel wire, plastic, seat belt, textile character
test.
20KN two columns metal tensile strength universal testing machine
with accurate extensometer adopts windows based interface, easy and
fast to reach different functions, suitable for most of operators
using habits. Integrated all common operation functions, like
specimen information input, specimen choosing, curve plotting, data
display, data process, data analysis, test operation etc., easy and
convenient to operate
