TDL8411

Thermal Dilatometer

Detects thermal expansion and contraction changes within samples with high reproducibility.

Utilizing a differential expansion method that cancels thermal expansion and contraction caused by the detection mechanism, this instrument enables precise and reproducible measurements, even for low-expansion materials or thin samples. An optional auto-sample changer can also be installed, contributing to energy savings and high throughput. Additional features include a built-in air-cooling fan to shorten cooling time after measurement completion and an automatic sample length measurement function.
