Four Probe DC Resistance measurement

The Electrical resistivity or specific electrical resistance and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows current. Both resistance and resistivity describe how difficult it is to make electrical current flow through a material, but unlike resistance, resistivity is an intrinsic property. Every material has its own characteristic resistivity. The system is designed by our company are most advanced in its specifications and can undertake various tests needed by researchers. The complete system is fully automatic with temperature variation and can go down as low as liquid nitrogen. The system also has option to go beyond room temperature with high temperature options such as 500K, 773K and 1073K.

Various tests performed

  • DC resistivity vs temperature in fixed intervals.
  • IV Current vs Voltage in fixed temperature intervals.
  • VI Voltage vs Current in fixed temperature intervals.

Optional tests performed

  • Magneto resistance measurement
