Overview of HEAT DISTORTION TESTER

This tester is used to evaluate the heat resistance of plastic.
By loading specified bending stress to the test specimen while increasing the test temperature of the oil bath at a certain rate, the operator is to report the temperature at which the test specimen reaches standard deflection.
The tester can also conduct the VICAT softening temperature test.
A space-saving tabletop model (No.148-HD-T) is also available.

Overview of HIGH TEMPERATURE HEAT DISTORTION TESTER

This tester adapts the air circulating heating system to test the heat resistance of plastic (usually super engineering plastic) up to 500 °C.
The specimen racks are made by glass quartz to prevent measuring disturbances due to the deflections of the racks itself.
