Molten salt conductivity testerAs the core equipment for measuring key parameters of high-temperature molten salt systems, it has a wide range of applications in energy, chemical, metal smelting and other fields.
Molten salt conductivity testerAdvantages:
High precision measurement capability
Core advantages: Adopting the four electrode method or CVCC (constant voltage constant current) method, effectively eliminating electrode polarization effects, with measurement accuracy up to 1.5%, high resolution, and the ability to capture small changes in molten salt conductivity.
Application scenario: In the development of molten salt reactors, it is necessary to accurately monitor the ion conductivity characteristics of molten salt electrolytes (such as FLIBe salts) to ensure the safe operation of the core; In high-temperature molten salt batteries, conductivity data is directly related to battery charging and discharging efficiency.
Wide temperature range adaptability
Technical support: Equipped with a high-temperature electric furnace (such as RYD-2 type, which can reach 1000 ℃), using high-temperature resistant materials (such as platinum rhodium alloy electrodes and ceramic crucibles), supporting the full measurement of molten salt from melting to high temperature state.
Typical case: In solar thermal power generation, nitrate molten salt (such as binary salt 60% NaNO3+40% KNO3) works at 565 ℃, and the tester can monitor its conductivity stability in real time.
Multi functional integrated design
Extension function: Some models (such as RYD-2) integrate a primary crystallization temperature measurement module, which analyzes the solidification point of molten salt through the step cooling curve method, providing dual data support for optimizing molten salt formulations.
Efficiency improvement: A single experiment can simultaneously obtain conductivity and initial crystallization temperature, reducing equipment switching time and suitable for rapid screening of molten salt formulas in the laboratory.
Convenience and safety of operation
Pre assembled components: electrode guided molten salt conductivity pool components achieve rapid installation and reduce operational complexity; Grating ranging technology ensures electrode positioning accuracy and avoids human errors.
Safety protection: The enclosed furnace design reduces the risk of high-temperature molten salt splashing, and the thermocouple positioning device prevents damage to the temperature measuring element, ensuring the safety of experimental personnel.
Data reliability assurance
Temperature compensation function: Equipped with high-precision temperature sensors (such as K-type thermocouples), combined with algorithms to compensate for the impact of temperature on conductivity, ensuring that the data meets the reference value at standard temperatures (such as 25 ℃).
Repeatability verification: In the aluminum electrolysis industry, by long-term monitoring of the conductivity of cryolite alumina melt, the repeatability error of the verification tester is less than 0.5%, which meets the process control requirements.
