Description

Technical Field

[0001] This utility model relates to the technical field of thermal conductivity measuring instruments, specifically a convenient thermal conductivity measuring instrument. Background Technology

[0002] A thermal conductivity meter is an instrument used to determine the thermal conductivity of materials. It obtains the thermal conductivity of a material by measuring and calculating the heat transfer process of a sample under specific temperature difference conditions.

[0003] Existing thermal conductivity measuring devices are often complex in structure and large in size, and the sample fixation method is limited. Different forms of test samples (such as powder, block, and sheet) often require additional clamps or accessories for fixation during the measurement process, which makes the operation steps cumbersome and the measurement efficiency low. When changing test samples, some devices require disassembling and reassembling the probe and fixing structure, which not only increases the difficulty of operation but also easily causes damage to the probe and affects the measurement accuracy.

[0004] Therefore, it is necessary to design a user-friendly thermal conductivity measuring instrument to solve the above problems. Utility Model Content
