Vertical Thermal Expansion Rate Measurement Device "DIL820 Series"
Measurement of thermal expansion in the vertical direction is possible! The highest sensitivity is guaranteed by a high-resolution inductive sensor (LVDT).
The DIL820 series (DIL 821/822) is a high-precision vertical dilatometer belonging to the DIL 820 series from TA Instruments. These models are equipped with a new optical encoder that has a resolution of 1nm, making them particularly suitable for the analysis of challenging samples. The DIL 822 employs true differential measurement technology, providing the best sensitivity and accuracy for CTE (coefficient of thermal expansion) in the market.
