FPP230A

FPP230A is a scanning four-probe resistance tester specially designed for photovoltaic applications. It can quickly and automatically scan samples up to 230mm in size to obtain square resistance/resistivity distribution information at different positions of the sample. The probe head uses ruby bearings to guide the tungsten carbide probe, ensuring high precision and long life. The dynamic test repeatability (close to the real scene) can reach 0.2%, which is the leading level in the industry. The ultra-wide measurement range of 1mΩ~100MΩ can cover most application scenarios, and can be widely used in many fields such as photovoltaics, semiconductors, alloys, and ceramics.
