Thermodilatometry is a thermal analysis technique in which a constant load is applied to a sample, and the amount of expansion and/or shrinkage of the sample is measured during heating. TDL 8411 was recently added to the lineup of the Thermo plus EVO2 series as a high-performance thermodilatometer using the horizontal differential expansion system. It is equipped with various new functions, including space-saving design, ECO mode for reducing standby power and an auto sample changer holding 24 samples.
Two types of instruments are available: a standard type with a maximum use temperature of 1100°C (the support tube and detection rod are made of SiO₂), and a high temperature type ranging up to 1500°C (the support tube and detection rod are made of Al₂O₃).
