    This instrument is to be used on Tensile or Universal testing machines to find out

    Proof stress & Young’s modulus values.In case of many brittle materials such

    as high carbon steels, alloy steels, light aluminium & magnesium alloys, it is

    difficult to get yield values. For such materials stress corresponding to a certain

    allowable amount of plastic deformation is termed as proof stress say 0.1% or

    0.2% proof stress. The measuring range is upto 5mm & resolution is 0.001mm.

    Standard two fixed gauge lengths of 25 & 50 mm is provided. Different sizes

    gauge lengths can also be given at an additional cost. If this extensometer is

    ordered with a computerized UTM, then a special menu driven application

    software is provided, which accepts load & extension values, & evaluates

    proof stress values. The measurement accuracy satisfies all requirements

    of class-I as per IS:12872-1990.
