- Stuhings HFM-2700 is an ultra-high temperature steady-state heat flow thermal conductivity meter.
Mainly used for thermal conductivity testing of high-performance insulation, temperature-resistant and other materials.
Designed with reference to testing standards such as ASTM-D5470, when the hot and cold surfaces of the test sample are in a stable temperature field, the center area of the test sample and the center area of the heat flow measurement device will establish a unidirectional structure similar to that existing in an infinite flat plate. Steady state heat flow. The equivalent thermal conductivity of the tested sample is obtained by measuring the heat flux density, the hot and cold surface temperatures of the sample, and the sample thickness.
It adopts an exclusive thermal field design and has a special-shaped carbon composite heating element, taking into account temperature uniformity and stability. It adopts patented temperature control technology to achieve precise temperature control of ±0.1°C, and the rapid temperature rise capability takes only 5 seconds from low temperature to ultra-high temperature. Seed.
It is easy to operate and easy to use, has strong scalability, and supports diverse atmosphere customization.
