HDIL-1 / HDIL-2 Thermal Dilatometer (DIL)

This equipment is utilized for detecting solid inorganic materials and assessing the high-temperature expansion properties of metallic substances. It is particularly suited for analyzing corundum, refractory materials, shell and core materials used in casting, ceramics, porcelain clay, glaze, glass, graphite, carbon, and printed inorganic materials. Additionally, it offers essential testing capabilities for scientific research and educational purposes. Users can customize specimen atmosphere protection, including vacuum conditions up to 0.1 MPa, to meet specific requirements. Moreover, it adheres to standards such as GB/T3810.9 and GB/T3810.10-1999 for determining the linear thermal expansion of ceramic tiles.

Instrumental Characteristics of Dilatometar (DIL)

01

USB or RS232 serial communication interface, easy to connect with a laptop.

02

Self-heating rate experiments set by the user, PID control linear heating.

03

Instrument calibration standard samples of the indicators.

04

Measurement process automatically, automatic drawing, can also be manually corrected, the computer automatically calculates the coefficient of expansion, expansion coefficient of linear expansion volume, rapid thermal expansion.

05

Imported linear bearing drive to achieve expansion value without friction transmission, transmission accuracy and repeatability.
