Loresta FX: Precise resistivity measurement for research and quality assurance in defense
In modern materials research, industrial quality assurance and the defense industry with safety-critical applications One thing is crucial: absolute measurement accuracy. This is precisely where the Loresta FX – a portable four-point measuring device for the precise determination of the resistivity of conductive materials. Whether in the laboratory, in the field, or in the development of protective materials for military applications, the device impresses with its versatility, robust construction, and ease of use.
Thanks to its compact design and integrated battery, the Loresta FX is suitable for both stationary and mobile testing. Measurement results can be read directly on the display or easily downloaded and processed via the USB interface. This allows the device to be seamlessly integrated into existing laboratory processes and quality assurance procedures – a real advantage for research teams that need to work quickly and reliably.

Exact results for complex materials
The basis of the measurement technology is the proven Four-point method, which significantly reduces contact-related measurement errors and delivers reproducible results. With a measuring range of 10⁻² to 10⁴ Ω, the Loresta FX is ideal for Materials with medium to high resistivity. These include conductive polymers, carbon or graphite coatings, as well as metallized plastics or fibers.
Particularly practical: By using interchangeable measuring heads, the device can be individually adapted to different sample types – even with irregular geometries or small-format samples, the measurement accuracy is maintained.
Reliable technology for safety-critical applications
In defense research or sensitive industrial areas, the reliable characterization of conductive materials plays a central role. The Loresta FX is frequently used here to test EMC shielding materials or to evaluate the suitability of new materials with regard to electrostatic discharge. It is also used in the development of conductive housing coatings – for example, for Drones or mobile communication systems – the device provides crucial data in early development phases.
In field use, the Loresta FX demonstrates its strengths through high mobility and ease of use. Whether for rapid validation of protective materials or improvised shielding tests – the device enables reliable results directly on-site, even under realistic operating conditions.
Perfectly tailored to the needs of modern research teams
Research institutions, semiconductor companies, and high-tech manufacturers particularly value the Loresta FX's high measurement accuracy, ease of use, and versatile application possibilities. The device can be used without any problems even under extreme time pressure and strict audit requirements. The USB connection enables straightforward evaluation and documentation – a must for teams working according to international standards.
Conclusion: Precision meets practice
The Loresta FX combines state-of-the-art measurement technology with a practical design. It is the ideal tool for anyone who wants to analyze conductive materials not only precisely, but also flexibly and efficiently. Especially in dynamic application scenarios – whether in development or in the field – it enables reliable, immediately available results.
