DS-302 Mechanical Residual Deformation Instrument of Reinforcement Bars

DS-302 steel bar deformation instrument metal material testing
 
The calibration instrument equipped on this DS-302 Mechanical Residual Deformation tester for material testing is GWB-200B High precision extensometer calibrator (Measurement Span: 0~25mm; Resolution: 0.0002mm).

Applicable Standards: Meet requirement 'JGJ107-2010 Technical specification for steel bar mechanical connection'.
 
  • Using our self-developed DS-302 high precision deformation measurement instrument. The circuit part adopts high-precision A/D sampling chip. It can real-time display the actual deformation value from the two extensometers. The results are stable and reliable.
  • With the elastic connection (for example: spring and the rubber band cover) between the extensometers at two sides and the steel bar, specimen clamping is convenient and the instrument can have a long service life.
  • Two extensometer measurement range of this Mechanical Residual Deformation Instrument of Reinforcement Bars are selectable. Range 50/100/250mm. Span 10mm.
  • The DS-302 Material Testing Residual Deformation Instrument is composed of two high precision electric extensometers. They have the consistent sensitivity and are symmetrical installed.
  • The instrument can directly measure the average deformation on both sides of the sample. The measurement results are accurate.
  • The material testing deformation measuring instrument can save and inquire the deformation value of the test according to the number.
  • With a RS232 communication serial port, the current deformation value can be transmitted to the computer and displayed in real time.
