How does the RMS-1000C eliminate the massive thermal EMF errors found in standard 1000°C resistivity testing?

At 1000°C, the junction between the sample and the electrodes generates massive thermoelectric voltages (thermal EMF) that completely distort nano-ohm (nΩ) level resistivity readings. The MatMeas RMS-1000C utilizes a specialized dynamic current-reversal 4-wire method that mathematically cancels out all thermal EMF, delivering absolute precision for carbon, metal, and advanced oxide conductors.

Why do carbon and metal samples fail in conventional high-temperature resistivity fixtures?

Testing carbon or metals at 1000°C in open air results in instant, catastrophic oxidation, destroying the sample before data can be collected. The RMS-1000C integrates a high-vacuum and multi-atmosphere control chamber, enveloping the sample in a highly pure inert or reducing environment to ensure flawless, continuous conductivity mapping up to 1000°C.

What is the primary measurement principle of the RMS-1000C?

The RMS-1000C utilizes the four-wire (Kelvin) resistance measurement method to determine the resistivity of conductive materials. This method applies a constant current through two outer electrodes and measures the voltage drop across two inner probes, effectively eliminating contact and lead wire resistance to achieve nΩ-level precision under varying temperatures.

What sample shapes and forms are supported?

The system supports standard sample geometries including solid blocks, circular thin-sheet discs, and rectangular bars with specialized test fixtures.

Does the RMS-1000C comply with international laboratory standards?

Yes, all measurements fully align with international norms such as ASTM, IEEE, and GB/T standards to deliver publishable, research-grade data.
