Product Description
PCY-D-III Ultra-low Temperature Thermal Expansion Coefficient Tester Meter Testing Machine
Product Introduction
This instrument tests the low-temperature linear expansion coefficient according to the standard "GJB1875-94 Test Method for Thermophysical Properties of Rigid Foam Plastics". It measures the ultra-low temperature average linear expansion coefficient of various solid materials using the ejector method with imported high-precision micro-sensors to detect sample deformation values at different temperatures. Computer technology automatically completes detection, control, calculation, printing, and storage functions.
