FAQ
How does the DMS1000 eliminate AC interference and thermal lag common in standard high-temperature fixtures?
Standard high-temperature furnaces suffer from massive AC electromagnetic interference and significant thermal lag between the thermocouple and the sample, skewing dielectric data. The MatMeas DMS1000 eliminates this with a built-in sealable metal shielding system and a coplanar temperature sensor design, ensuring absolute thermal accuracy and 0.05% measurement precision up to 1000°C.Why do conventional measurement fixtures fail to provide pure dielectric data under varying atmospheres?
Conventional open-air fixtures allow sample oxidation at high temperatures, completely ruining the intrinsic dielectric response of the material. The DMS1000 features a highly specialized, sealable sample chamber that perfectly supports inert, oxidizing, reducing, and vacuum atmospheres, guaranteeing pristine electrical characterization of advanced ceramics.What components are included in the complete turnkey DMS1000 high-temperature dielectric measurement setup?
MatMeas delivers a complete turnkey, ready-to-test system including: (1) High-temperature sealed vertical furnace (RT to 1000°C, 800°C continuous); (2) High-purity platinum electrode sample fixture with coplanar thermocouple; (3) Intelligent multi-segment PID temperature controller (±0.5°C accuracy); (4) Precision wideband impedance / LCR core engine (1 Hz / 10 Hz to 10 MHz or 30 MHz); (5) Automated measurement and analysis software suite with real-time εr, tan δ, and Nyquist plotting; (6) Complete workstation accessories, pre-configured Dell PC, low-noise shielded BNC cables, and standard BaTiO3 reference samples.Can the system measure multiple samples simultaneously under controlled atmospheres?
Yes. The DMS1000 features a highly versatile measurement platform capable of evaluating a single sample (up to 30 MHz) or up to four samples simultaneously (up to 10 MHz). Its sealable furnace design supports a wide range of environments, including inert, oxidizing, reducing, and vacuum atmospheres.How does the equipment protect delicate ceramic samples while maintaining reliable electrical contact?
The system incorporates high-purity platinum electrodes to ensure low contact resistance and oxidation resistance at high temperatures. Additionally, each unit undergoes strict factory calibration to apply a maximum sample pressure of only 0.25 N, securing bulk ceramic disks (including standard 10 mm diameter pellets) precisely without physical damage. For non-standard thin pellets (< 1 mm, such as 0.4–0.8 mm), customized low-force configurations and geometric capacitance correction are supported upon technical consultation. Furthermore, measurement reliability is strictly validated using standard Barium Titanate (BaTiO3) samples prior to delivery.
