Testing Function
Refractory conductors, graphites, and carbon-carbon composites deployed in metallurgy, chemical engineering, and hypersonic aerospace must maintain predictable electrical transport under extreme heat up to 1600°C. Our RMS-1650C system utilizes a precision Kelvin four-terminal bridge to cancel high-temperature lead resistance, delivering reliable resistivity curves for solid refractories as well as ionic conductivity of molten glasses.
