The RMS1650 Ultra-High Temperature Resistivity Measurement System is engineered for the rigorous electrical characterization of insulating and dielectric materials. Utilizing a proprietary guarded three-terminal electrode configuration—secured by a patented high-temperature fixture design (Patent No. 2019204134342)—the system complies with established testing protocols for determining elevated-temperature bulk and surface resistivity.

The instrument enables the precise, in-situ acquisition of resistance, resistivity, and leakage current degradation kinetics as a function of both temperature and time. Capable of operating under ambient air, vacuum, and flowing gas atmospheres, the RMS1650 is a premier analytical platform for evaluating extreme-environment insulation performance. It has been successfully deployed in the development of critical aerospace sensors and remains the system of choice for advanced high-temperature insulation research across leading academic institutes and industrial R&D centers.

At its core, the system features an imported refractory corundum (alumina) muffle chamber that resists oxidation and supports continuous operation up to 1600°C. A built-in metallic Faraday shield effectively attenuates external AC electromagnetic interference, working alongside a high-stability PID controller to achieve an exceptional thermal regulation accuracy of ±0.5°C. Pure platinum electrode fixtures ensure uncompromised corrosion and oxidation resistance, facilitating rapid thermal equilibration and stable ohmic contacts. Additionally, guarded analog signal routing minimizes parasitic capacitance and AC noise from the furnace heating elements, thereby significantly extending the test frequency bandwidth and data fidelity.
