G-003 Thermal Conductivity Tester (Guarded Hot Plate Method)
BACK
Standards:
Applications:
This instrument is mainly used to test the thermal conductivity of plate-like materials such as plastics, fibers, foams, thermal insulation materials, concrete, and refractory materials. With an additional sample frame, it can also test powder and paste materials. It is widely used in manufacturing enterprises of heat-resistant and thermal insulation materials, quality inspection departments, universities, and research institutes.
Product Information:
All measurement and control functions are computer-controlled, reducing human error and improving testing accuracy. The instrument uses a computer interface to realize fully automatic control, data acquisition and processing, as well as calculation, display, and printing of thermal conductivity results. It features short measurement time, fast operation speed, accurate data, and a high degree of automation.
