FAQ

  • How does the DMS2000 prevent moisture condensation and false water peaks 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.
