Mechanical Extensometers

Mechanical Extensometers (Model FXT-3)

It is an attachment to Universal Testing Machine and Tensile Testing Machines, used to find out the proof stress at the required elongation percentage.
It measures the elongation of a test piece on load for the set gauge length.
Least count of measurement 0.01 mm and maximum elongation measured upto 3 mm.
Adjustable gauge length from 30 mm to 120 mm
Round specimen from 1 mm to 20 mm dia and flat specimen from 1 mm to 20 mm thickness can be accommodated.
