Glass Thermal Expansion Coefficient Tester (Vertical)

Published: 3/14/2025

The PZY-III-1000 is a vertical, automated instrument for precise measurement of the thermal expansion coefficient of glass. It supports configurable heating profiles, digital data acquisition, printing, and archival for laboratory and industrial R&D use.

Product Description

The PZY-III-1000 Glass Thermal Expansion Coefficient Tester measures dimensional change of glass specimens under controlled heating to determine the thermal expansion coefficient. The system integrates an intelligent furnace controller with PID regulation and PC-based software for parameter setup, run control, visualization, and data management.

Its vertical architecture supports single or dual push-rod configurations and accommodates solid or powder samples (with optional molds). A quartz sample holder ensures thermal stability, while a high-resolution displacement sensor captures micro-scale expansion changes across programmable heating rates.
