ST2242 AC Four-Probe Meter for Electrical Analysis

The ST2242 handheld AC four-probe tester is a resistivity testing instrument specially designed for samples that are not suitable for testing by the DC four-probe method. It is mainly used for ionic conductive substances (such as electrolyte solutions, conductive gels) and conductive powder suspensions (such as carbon powder, graphene powder slurry). Adopting new digital and microprocessing technologies, the resistivity or resistance is measured by the precise 4-wire method and the simple 2-wire method. It has unique anti-interference ability and environmental adaptability, with good consistency in repeated tests, ensuring high precision, high stability and high reliability in long-term measurements. It is widely used in scientific research institutions and universities for testing the conductivity of gels, solutions, ionic conductive materials, and samples not suitable for direct current testing. The ST2242 AC four-probe resistivity tester consists of a main unit, a test bench, test p…
