FT-400AHXM Chemical Conversion Film Surface Resistance Tester

FT-400AHXM Chemical Conversion Coating Surface Resistance Tester Surface Resistance Meter

I. Product Features Introduction:

The four-point measurement method is applicable to manufacturing enterprises, colleges and universities, and research departments. Laboratory testing and analysis are used for chemical conversion materials applied to coated aluminum and aluminum alloys; as well as for the chemical conductive oxidation film layers of aluminum and aluminum alloys, which have specific requirements for surface contact resistance and resistivity measurement..

PCSoftware-operated interface, auto-run, automatically measure sample thickness to the thousandth place, real-time analysis of the resistance and pressure change curve diagram during the pressure application process, capable of displaying resistance, resistivity, and conductivity change diagrams, auto-generate reports.
