This low-temperature universal thermal conductivity meter operates within a temperature range of -30 to 100°C. Equipped with an automated control system, it supports automatic measurement at multiple temperature points. The instrument features high testing accuracy, fast measurement speed, precise temperature control, minimal sample requirements, and easy operation.
Compatible with various sample forms including blocks, sheets, powders, granules, pastes, and colloids, this meter meets the testing needs of multiple material types and sample forms without requiring sensor changes, significantly reducing measurement costs. It is widely used for measuring thermal conductivity of thermally conductive materials, phase change materials, composite materials, soil, rocks, and more.
