Precise resistance measurement with the Hiresta-UX resistivity meter

The Hiresta – UX measuring device is used to measure Semiconductors and non-conductors or insulators im high-resistance range. It is an extremely precise measuring device for measuring:

resistance [Ω]
Surface resistance [Ω/□]
volume resistance [Ω∙cm]

Versatile application possibilities

The Hiresta-UX is suitable for a wide variety of substances and materials of all shapes and sizes. By using concentric ring electrode measuring heads and the constant voltage method, a measuring voltage of up to 1000 V can be achieved at the measuring head. Thanks to the integrated “Auto Sweep” function, the device adapts the applied voltage to the resistance in 29 steps.

Precision through correction factors

The Hiresta-UX is used to determine specific resistances Correction factors, which depend exclusively on the geometry of the measuring head electrodes. This means that a correction of the measuring position is not necessary.

Measure surface resistance and volume resistance

The measuring device has a built-in switch box that allows quick switching between measuring the surface resistance and the volume resistance enabled. The volume resistivity [Ω∙cm] is measured in conjunction with the UFL Table (RMJ 354), which offers two reversible surfaces: a conductive metal surface and an insulating Teflon-coated surface.
