Product Description
The tester evaluates linear thermal expansion of polymer specimens by measuring length change over a specified temperature range. It supports automated testing, data recording, printing, and archiving through a Windows control computer and uses a quartz reference specimen for calibration.
PID control supports online measurement. The system can be used for thermal expansion, softening temperature, glass-transition temperature, and phase-transformation research under GB 1036-2008 and ASTM D696.
