Sheet Resistance Measurement

Single Point Measurement Devices

EddyCus® TF lab Series

  • +  Contact-free and real-time
  • +  0.001 to 1,000 Ohm/sq
  • +  Measurement of encapsulated layers

Sheet Resistance Measurement

The EddyCus® TF lab series testing devices are especially designed for single-point contactless real-time thickness and sheet resistance determination of low and high conductive thin films on glass, wafer,   plastics, or foils. The devices are also ap­pli­cable for real-time wall thickness measurements of conductive materials such as metal foils and sheets.

Applications

  • Architectural glass
  • Touch screens and flat monitors
  • OLED applications
  • Smart-glass applications
  • Transparent antistatic foils
  • Photovoltaic cells
  • De-icing and heating applications
  • Batteries
Transparent Thin Films Metallic Thin Films
TCO (ITO, AZO, FTO) Aluminum
Graphene Molybdenum
CNT (Carbon Nano Tubes) Zinc
Metal Nano Wires Silver
and many more and many more

Software & Handling

The EddyCus® TF lab control is a user-friendly software for sheet resistance measurement, data tracking, and data analysis. SURAGUS offers a touch screen software that is optimized with an according notebook or tablet PC to provide a system with high usability.
