HDT testing device (Load Deflection Temperature Tester)
Catalog No. 533
This is a testing machine for evaluating the heat resistance of plastic materials (load deflection temperature / DTUL, Vicat softening temperature, ball pressure).
■It is safe because there are no cooling pipes installed inside the oil tank. (※Water-cooled heat exchanger method) ■By adopting the heat exchanger method, the cooling speed is fast, allowing for a reduction in test cycles. ■With the optional use of a chiller, rapid cooling is possible even in summer when the temperature of tap water is high.
