Overview
📢 Official Platform Generation Upgrade Notice:
The RTS-1000C represents the official next-generation flagship evolution of the widely deployed RMS-1000C platform (originally Partulab / BaLab RMS-1000C in earlier literature citations). Built upon customer feedback from leading research institutes, the RTS-1000C introduces a newly engineered vertical motorized test stand, dense 99% Zirconia (ZrO₂) thermal isolation, upgraded dual-material platinum/tungsten-carbide probes, and guaranteed dynamic measurement from 10 nΩ to 100 MΩ.
The RTS-1000C High-Temperature Conductive Material Resistivity Test System is designed for the rigorous evaluation and electrical transport characterization of functional conductive materials across elevated temperature profiles. Built upon the four-wire (Kelvin) resistance measurement principle, the system measures resistance and volume resistivity curves as a function of temperature and time under vacuum or controlled atmosphere conditions.
Specifically engineered to overcome low-resistance measurement bottlenecks without data dropouts or post-hoc corrections, the RTS-1000C accommodates circular disc samples (Φ15–25 mm diameter), squares, and rectangular strip specimens (including specialized dimensional positioning fixtures for delicate 5×5×10 mm to 5×5×20 mm monoliths). It is extensively utilized in university laboratories and industrial R&D for carbon-based conductors (synthetic graphite, graphene, carbon black), metal alloys, conductive metal oxides, structural conductive polymers, superconducting materials, and advanced composites.

FAQ
How does the RTS-1000C differ from the earlier RMS-1000C platform?
The RTS-1000C is the official next-generation flagship upgrade to the earlier RMS-1000C platform (originally cited in literature as Partulab / BaLab RMS-1000C). Key advancements include: (1) an integrated vertical motorized test stand replacing earlier multi-piece chassis; (2) dense 99% Zirconia (ZrO₂) isolation components replacing older alumina/ceramic supports for superior oxidation resistance; (3) a hybrid Platinum and Tungsten Carbide electrode system for superior ohmic contact; and (4) a factory-calibrated 10 nΩ to 100 MΩ measurement range backed by real-time software fault diagnosis.What is the primary measurement principle of the RTS-1000C?
The RTS-1000C utilizes the four-wire (Kelvin) resistance measurement method to characterize bulk resistance and resistivity. By separating current injection leads from high-impedance voltage sensing probes, the system completely eliminates contact resistance and cable lead errors, ensuring stable data down to 10 nΩ.How does the system prevent sample oxidation during elevated temperature testing?
The system features a sealed vacuum/atmosphere chamber allowing testing under high vacuum or with continuous inert gas purge (such as high-purity argon or nitrogen). This completely protects oxidation-prone carbon composites, metallic alloys, and nanomaterials from degradation up to 600°C.Why are 99 zirconia insulation components used in this system?
Conventional alumina or quartz supports can exhibit surface degradation and electrical leakage at elevated temperatures. The RTS-1000C incorporates dense 99% Zirconia (ZrO₂) insulation, ensuring superior oxidation resistance, mechanical stability, and high electrical isolation at high temperatures.What sample shapes and dimensions are supported?
The standard measurement fixture accommodates circular disc samples ranging from 15 mm to 25 mm in diameter, as well as square blocks and rectangular strips. Customized dimensional positioning fixtures are available for small rectangular bars such as 5 × 5 × 10 mm and 5 × 5 × 20 mm.Can the RTS-1000C measure fragile or porous 3D-printed ceramic monoliths without sample breakage?
Yes. For porous, mechanically delicate specimens (such as 3D-printed CaCO₃/CaO-based ceramic monoliths containing conductive additives), MatMeas provides a specialized low-pressure elastic electrode fixture. The spring-loaded mechanism is positioned in the low-temperature cold zone, isolating mechanical spring fatigue from high-temperature relaxation. This guarantees constant, low-contact pressure and fixed electrode spacing across RT to 1000°C under controlled N₂/inert atmospheres without fracturing delicate porous structures.Can the system be extended to 1000°C for small rectangular bar specimens?
Yes. While the standard configuration is optimized for RT–600°C and Φ15–25 mm discs, the RTS-1000C platform offers an optional 1000°C High-Temperature Controlled Atmosphere Package with customized dimensional positioning fixtures. This configuration reliably supports rectangular monoliths (such as 5 × 5 × 10 mm and up to 5 × 5 × 20 mm) for DC four-wire R(T), ρ(T), and σ(T) characterization under inert nitrogen or argon purge.What is included in the standard factory configuration?
The standard system includes the main unit with integrated furnace, dedicated four-wire measurement fixture, proprietary data acquisition and analysis software, standard sample toolbox, factory calibration/inspection report, power cord, and user manual.
