Hiresta-UX resistivity meter

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.

Protective shield technology for precise results

In order to avoid incorrect measurements due to external influences and leakage currents, the Hiresta-UX resistivity measuring device uses a special protective shield technology (guard technology). This technology requires a third connection between the measurement object and the measuring device, which acts as a protective electrode and offers a continuous reference potential for shielding.

User friendly design

The compact design of the Hiresta-UX resistivity meter, combined with a color 7.5″ TFT touch display and user-friendly menu navigation, ensures simple and intuitive operation.

Measuring head holder for URS measuring head (RMJ-360)

The URSJG measuring head holder fixes and presses the URS measuring head reliably onto the sample due to its weight. The advantage is that the measuring head does not have to be held by hand during the measurement.

UFL Table (RMJ 354)

Insulating surface for the Hiresta and Loresta series with 2 reversible surfaces (metal surface / Teflon coated surface) for measuring volume resistance. The stainless steel metal surface serves as a second electrode (dimensions: 240mm x 140mm).

Further application examples for the Hiresta-UX

1. Development of antistatic and insulating plastics
   In the plastics industry, the Hiresta-UX is used to test insulating materials for electronics packaging. The goal is to ensure a surface resistance above 10¹² Ω/□ to reliably prevent electrostatic discharges.
2. Characterization of display and touchscreen materials
   For optically transparent insulators or dielectric layers in capacitive sensors, the volume resistance is measured to avoid leakage currents and increase the service life.
3. Testing of protective coatings in the semiconductor industry
   Thin layers of polyimides or siloxanes, which serve as electrical insulation, are tested for their long-term stability and high resistance to breakdowns.
4. Analysis of insulating films in batteries or supercapacitors
   Separator films must have an extremely high volume resistivity (10¹³ Ω·cm and more) to prevent internal short circuits – the Hiresta-UX allows fast, non-destructive testing of this property.
5. Materials research on polymer materials for medical technology
   In the development of sterile, electrically insulating materials for sensors and devices (e.g. ECG electrode housings), measuring surface resistance is a crucial quality step.
