Welcome to the official website of Beijing Leadlong Technology Co., Ltd
ALC-48 Thermal Expansion Tester is a new generation of high-performance mechatronics intelligent products, which is used to measure linear expansion coefficient of materials in carbon, metallurgy, cement and other industries.
Instrument characteristics: This product meets the requirements of ISO14420 2005 and YS/T764-2011.
● Special control software and human-machine interface of high-definition touch screen can choose different measurement methods. Display real-time expansion curve and temperature curve in the measurement process; the system automatically calculates, displays, and stores measurement results of expansion rate; the system reserves data network transmission function, which can realize centralized management and real-time sharing of data.
● The system adopts the heating furnace pneumatic control rising and decreasing technology, which has fast response speed and accurate positioning. The measuring frame is firm and not easy to deform, ensuring the accuracy of measurement results.
● Adopting high precision and low temperature drifting micro-displacement sensor with measurement accuracy of 0.1 um.
● Two-mode temperature measurement method can measure thermal expansion coefficients at 300 ℃ and at room temperature to 960 ℃. When measuring samples that may react with air at high temperatures, protective gas should be supplied in the 960 ℃ working mode.
