Overview

M2 Handhold four point probe tester is a comprehensive multi-purpose measuring device, which used the four-probe measurement principles. Which can measure resisitivity and sheet resistance of the flake, massive semiconductor material in radial and axial. After put on a special four point probe test fixture, M2 also can measure the low and medium resistance of the metallic conductor.

M2 is componented by main equipment and test probe (optional testboard). The test results can be displayed directly. The main equipment is componented by Numerical control constant current source, high-resolution ADC, embedded microcontroller system. Can be conversion range automatically . Test probes are made by high wear-resistant tungsten carbide, Which kind of probe positioning accuracy, wavering smaller, long life.

M2 applies to the semiconductor material, semiconductor device factory, research institutes, colleges and universities on the resistance properties of semiconductor materials testing. Especially for applications that require fast measurements of low resistivity of the occasion.

Working atmosphere conditions of this instrument is shown as following:

Temperature:25°C±2°C

Relative humidity:60% ~ 70%

There is no strong electric field interference in the working room of this instrument, which is far away from the high frequency equipment.
