As a specialist Electronic Extensometer manufacturer, Fine Spavy Associates & Engineers supplies and exports to industrial buyers, QA laboratories and inspection departments across Nepal, serving the hydropower, construction and steel sectors. Machines are built to ISO 9513, ASTM E83 and align with NS, ISO, ASTM practice followed in Nepal, then shipped CIF to Kolkata Port (transit to Birgunj).
• 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.
