Automatic High Temperature Carbon Materials Hot Resistivity Test Machine Laboratory Electrical Hot Resistivity Meter
Equipment Overview:
This instrument's core technical specifications are customized according to standard requirements. It features automatic heating, automatic electrode raising and lowering, automatic real-time recording of resistance values at different temperatures, and the ability to plot test curves, export data, and save electronic reports. It boasts high measurement accuracy, convenient operation, and a high degree of intelligence.
Test Principle:
This method utilizes the four-probe method to test resistivity. Under a specific temperature environment, four probes contact the surface of the sample. A constant current source provides an appropriate current to the two outer probes, and the voltage across the two middle probes is measured. The hot resistivity is then calculated using Ohm's law.
Equipment Application:
This instrument measures the resistivity of a sample under high-temperature vacuum or atmospheric conditions after reaching the set temperature at the set heating rate.
