| Description | This optical dilatometric measurement method used in DIL 806 is an absolute process, entirely independent of any possible expansion or contraction of the instrument. Consequently, measured results do not need to be corrected or calibrated for different temperature programs. Coupled with the fast This optical dilatometric measurement method used in DIL 806 is an absolute process, entirely independent of any possible expansion or contraction of the instrument. Consequently, measured results do not need to be corrected or calibrated for different temperature programs. Coupled with the fast response of the DIL806 furnace, this makes the system particular well-suited for the analysis of dynamic processes that involve multiple temperature steps and dynamic heating rates.A high-performance LED emits a broad-width planar light beam onto the sample. The sample shadow is detected by a high-resolution CCD sensor. The signal is then evaluated by a digital edge-detection processor which provides a sensitive and precise measurement of dimensional change. This principle is known as the shadowed light method and provides an accurate and absolute measurement of the sample dimension with changing temperature....

Measuring only the difference between the sample and the reference specimen, the For highest measurement accuracy, the DIL 802/802L provides a truly differential measurement in a horizontal dilatometer.For highest measurement accuracy, DIL 802 and DIL 802L provides a truly differential measurement. Measuring only the difference between the sample and the reference specimen, the True Differential design negates the influence of measurement system expansion on the sample measurement. This measurement design is of particular benefit for dynamic temperature programs such as those employed in Rate-Controlled-Sintering (RCS) and for measurements at lower temperatures. The DIL 802 is designed for measurements under vacuum or inert gas while the DIL 802L is designed for measurements under air....

An instrument Packed with automated features, the DIL 831 features the patented 1 nm resolution optical encoder, a family of new dynamic furnaces, and the new linear sample load motor. The result is the best performing horizontal single sample push-rod dilatometer available on the market.
An instrument offering scientists the ideal tool for R&D laboratories to measure the linear thermal expansion and to calculate the Coefficient of Thermal Expansion (CTE) of ceramics, glasses, high performance materials, polymers, metals and alloys with great accuracy.
Features include: - Linear motor for a sample load range of 0.01 to 1.00 N, with a force resolution of 0.01 N and linearity better than 0.01 N across the total measuring range of 5000 µm, to guarantee the correct sample load regardless of the material tested.
- Patented optical incremental encoder to bring length measurement resolution down to a best in class 1 nm, and to allow the measurement of shorter samples yet preserving an outstanding ?L resolution. Its newly designed measuring head housing and the active electrical thermal stabilization ensure unprecedented stability of the detection core. This, combined with the unique design of TA Instruments furnaces, results in a zero temperature-gradient across the specimen and an industry leading CTE accuracy for single sample push rod dilatometers of 0.03 x 10-6 K-1.
- Automatic recording of the initial sample length.
- Water cooled furnaces providing a very dynamic temperature programming with a maximum heating rate of 50 K/min and industry unmatched cool down time of 13 minutes from 1000°C to room temperature. *This is up to 15 times shorter than competitive instruments.*
- Integrated electronics providing network connection, while the integrated touch screen allows you to perform many functions directly on the instrument and shows, in real time, measurement parameters and test’s time-to-completion.
