SIGMATEST probes

Flexible conductivity probes for precise testing of non-ferromagnetic metals

Reliable measurements for every geometry. . The SIGMATEST probes are designed for precise electrical conductivity measurements in combination with the SIGMATEST measuring instrument. Together, they form a complete system for reliable testing of non-ferromagnetic metals across a wide range of applications.

Different probe geometries enable flexible use on various component shapes and testing positions. Standard, angled and flexible-arm probe versions are available, as well as customized solutions tailored to specific application requirements.

The probes are available in diameters of 5 mm, 8 mm and 14 mm. The 14 mm probe offers improved handling and highly stable readings due to its larger contact surface, while the 8 mm version is ideal for narrow or small surfaces such as coins or small components.
