General Properties: This apparatus used for determining the length changes  was originally designed for use on concrete structures, but can also be conveniently used for any other type of structure including steel. The test set includes the extensometer with digital gauge resolution 0.001 mm, standard bar, calibration bar, 50 datum discs, adhesive compound for datum discs and carrying case.
Two models available: 100 and 300 measuring base.
Mechanical strain gauge for the measurement of length variation. Measuring base 100 mm x 5 mm range. Digital gauge, 0.001 mm resolution, output for PC connection (special cable required, see accessories)
Mechanical strain gauge for the measurement of length variation. Measuring base 300 mm x 5 mm range. Digital gauge, 0.001 mm resolution, output for PC connection output for PC (special cable required, see accessories)
