Electrical Properties Measurement System
This Electrical Properties Measurement System is used for electrical testing of functional materials such as ferroelectricity, piezoelectricity, pyroelectricity, dielectricity, insulation resistance, etc. in high and low temperature environments.
Many adaptive interfaces have been made with international electrical testing instruments in terms of communication protocols, database processing, and software compatibility. This makes this set of instruments easier to expand in the future, both in terms of software and hardware and saves more time and hardware costs for transformation.
