FAQ
How does the DMS2000 prevent thermal frosting and false water peaks near 0°C during cryogenic testing?
When standard dielectric fixtures are cooled with liquid nitrogen, atmospheric moisture condenses and freezes on the sample, creating massive false 'water peaks' in the impedance data near 0°C. The MatMeas DMS2000 fundamentally solves this by incorporating a proprietary vacuum-enabled sample chamber, strictly isolating the sample in a high-vacuum environment to guarantee 100% frost-free, artifact-free data from -160°C to 450°C.Why is the DMS2000 more stable than traditional liquid nitrogen bath cryostats?
Traditional immersion cryostats suffer from severe temperature fluctuations caused by the boiling off of liquid nitrogen, leading to noisy dielectric measurements. The DMS2000 utilizes an advanced, proprietary LNP-95 liquid nitrogen injection and vaporization system that provides ultra-smooth, continuous temperature variation (±0.5°C accuracy) without the mechanical vibration or thermal shocks of boiling baths.How does the DMS2000 prevent thermal frosting and false water peaks near 0°C during cryogenic testing?

Moisture interference is a critical issue in low-temperature measurements. The DMS2000 completely resolves this by utilizing a specialized vacuum-enabled sample chamber. This design provides exceptional thermal insulation, strictly preventing sample frosting and eliminating the occurrence of false water peaks near 0°C.What is the advantage of the DMS2000's specific electrode design for solid samples?
Developed based on the parallel plate capacitor principle, the system utilizes a highly innovative electrode configuration: a hemispherical upper electrode paired with a flat lower electrode. Combined with high-purity precious metal electrodes, this ensures improved physical contact, outstanding oxidation resistance, and minimal contact resistance under extreme temperatures.What are the measurement throughput and frequency capabilities of the system?
The highly integrated DMS2000 platform supports variable research needs. It offers a single-sample testing configuration with an ultra-wide frequency range from 20 Hz up to 30 MHz. Additionally, it provides a high-throughput configuration capable of measuring five bulk samples simultaneously across a frequency range of 20 Hz to 10 MHz.How does the system ensure operational safety during liquid nitrogen cooling?
The DMS2000 is equipped with a built-in mechanical pressure relief device to ensure safety under overpressure conditions. Furthermore, it features a liquid level alarm function that automatically alerts operators when the liquid nitrogen falls below the minimum required level.
