The TCT-3L heat flow thermal conductivity meter is designed and manufactured in accordance with the ASTM D5470-2017 standard. Our company has accumulated more than ten years of experience in manufacturing and user practice for this product, which has enabled the product's performance to be continuously improved and matured. It adopts servo motor to control precise automatic pressurization and automatic thickness measurement device, and is connected to a computer to achieve fully automatic control. The instrument uses 6-point temperature gradient detection to improve test accuracy. A protective thermal device (thermal protection of the sample) is added around the test rod in the test head to reduce the impact of ambient temperature on the test. It can detect thermal resistance curves under different pressures, adopt optimized mathematical models, and measure multiple parameters such as material thermal conductivity and thermal resistance, as well as contact thermal resistance at the interface. The latest technology is used to automatically compensate the cold end temperature, eliminating the need to add ice water compensation device. The latest technology is used to automatically compensate the cold end temperature, eliminating the need to add ice water compensation device.
Note:
Users can choose standard or small models (with the same performance) according to the actual floor space to save laboratory space.
