1、 Overview of functional and structural features

Basic function: ST2258H metal mass resistivity tester is a multi-purpose comprehensive measuring device that uses the principle of parallel four knife method (four terminal method) to professionally measure the (mass) resistivity/square resistance of metal foil samples.
Basic composition: The testing instrument consists of ST2258H mass resistivity tester (host), SZT-H1 test bench (parallel four electrode), and ST2258H mass resistivity testing PC software.
According to the standard: "GBT 5230-1995 Electrolytic Copper Foil Appendix C Electrical Performance Inspection Method - Mass Resistivity Test Method", refer to "GBT 3048.2-94 Electrical Performance Test Method for Wire and Cable - Metal Conductor Material Resistivity Test"
Advantages and features: This testing system is equipped with supporting PC software, which makes parameter settings, data testing, and other operations simple and clear. The functions of data testing, collection, editing, saving, printing, and historical query are complete.
This system can be operated online with PC software or offline with individual instruments, with simple and complete functions.
Application scope: This instrument is suitable for testing the mass resistivity/resistivity/square resistance performance of metal foil materials in factories such as metal foil, thin film materials, capacitor factories, research institutions, and universities. It is also suitable for conducting resistivity and square resistance tests on thin films, thin layer conductors, and semiconductor materials using the parallel four knife method.
