Resistivity measurement system is a set of Holzer effect, magnetoresistance, I-V characteristictest in one of the automatic test system. The system fully considered the instrument configuration, the circuit connection (including connection and low temperature chamber) and other users often ignore the problem, select the electrical measuring instrument AmericanKeithley, magnetic field according to user needs by electromagnet or without liquid heliumsuperconductive magnet, equipped with measuring sample rod smart, full automation special test software plus, can let the user sample test quickly and easily, and get the accurate and reliable data. In addition, there are a variety of cryogenic system options, and can carry outspecial modification of existing instruments according to user requirements and the specialsoftware, is a powerful tool for scientific researchers to study the resistivity measurements on samples.

The main features of resistivity test system:

1) standard system uses plug-in sample sample fixture, easy installation;

2) the basic configuration at a time can be attached with four samples, and also can be testedon a sample of two;

3) standard system of random distribution of a probe sample card;

4) standard measurement system can I-V characteristics of the Holzer effect, under thedifferent magnetic field;

5) resistance and wide measurement range: 0.1M Omega - Omega 50G (high resistancesystem), the uncertainty of measurement is 2%;

6) test procedure and calculation process is automatically performed by the software, and save a lot of time;

7) software can display the measurement results and measuring curves;

8) the closed-loop control system can provide high stability of the magnetic field, magnetic field, and solves the problem of realizing zero magnetic field magnet remanence, real;

9) select the variable temperature options, can be measured Holzer effect measurement andthe characteristics of I-V under different temperature.
