SYA-32A Heat Flux Method Multifunctional Thermal Conductivity and Thermal Resistance Testing Instrument

Description

Product Introduction:

Product Features:

A protective thermal shield has been added around the test rod inside the testing head (this device provides thermal protection for the specimen), thereby extending the instrument’s temperature measurement range and reducing the influence of ambient temperature on the test results.
A thermocouple array for measuring temperature differences in the thermal‑flux test has been added to the test rod inside the test head, enhancing the resolution, accuracy, and repeatability of thermal‑flux measurements.
The use of an ice–water mixture for thermocouple cold-junction compensation has been eliminated, simplifying operation and enhancing user convenience.
Experimental methods such as “aging reliability testing,” “high‑thermal‑conductivity material testing,” and “inter‑sample contact thermal resistance testing” have been added.
