PROMET SE+ – Portable Microohmmeter
The PROMET SE+ is a compact, battery-powered microohmmeter for high-precision resistance measurements in the microohm range. With test currents of up to 200 A, the device is ideal for measuring contact and contact-to-ground resistances in switchgear, substations, and industrial power supply systems. Thanks to four-wire technology (Kelvin measurement), the PROMET SE+ delivers reliable and reproducible measurement results—both in mobile, standalone use and when integrated into ACTAS switchgear test systems.

Your Benefits with the PROMET SE+
• Portable and self-contained: Battery-powered for flexible use without an external power supply.
• Precise measurement results: Four-wire technology minimizes the influence of cable and contact resistance.
• Test currents up to 200 A: Ideal for reliably evaluating contact and transition resistance.
• Parallel measurement at two test points: Less need to reconnect test leads, faster test procedures, and better comparability of results.
• ACTAS-compatible: Can be used as a standalone device or fully integrated into ACTAS switchgear test systems—including static and dynamic resistance measurements.
• Rugged and lightweight: Weighs only 1.5 kg and features IP54 protection for daily use in the field.
• Digital documentation: Result management, creation of test reports, and Excel export for efficient evaluation.

Software
The PROMET operating software is available for the PROMET SE+ to read and manage measurement results. It provides a clear overview of the measurement data and allows users to create professional test reports, including Excel exports. In addition, the microohmmeter can be fully integrated into ACTAS switchgear test systems, where it supports both static and dynamic contact resistance measurements.
