KoCoS launches PROMET SE+ micro-ohmmeter for mobile resistance testing

KoCoS Messtechnik AG has introduced the PROMET SE+, a new generation of its mobile resistance testing system designed to detect critical contact issues early and fit into professional switchgear testing workflows. The device keeps the core capabilities of the PROMET SE while adding battery-powered operation, touchscreen control and broader field-use flexibility.

Why it matters: - The PROMET SE+ is aimed at early detection of critical contact issues in switchgear testing. - Mobile field testing teams can use the system without an external power supply. - Existing ACTAS users can add new functionality without replacing established equipment.

What happened: - KoCoS Messtechnik AG introduced the PROMET SE+, a new micro-ohmmeter for mobile resistance testing. - The launch took place in Korbach, Germany, on June 18, 2026. - The device is presented as the next generation of KoCoS' PROMET SE measurement system.

The details: - The PROMET SE+ retains microohm resistance measurements with test currents of up to 200 A. - The system still supports simultaneous measurement at two test points. - The device remains integrated into ACTAS test systems. - KoCoS kept the established operating concept and provides access through a graphical user interface. - An integrated lithium-ion battery allows operation independent of external power. - A 5-inch touchscreen supports direct control and on-site evaluation of measurements. - A LAN interface with a PHOENIX VS/NBC connector is included for data communication. - KoCoS designed that interface for industrial operating environments.

Between the lines: - The product update focuses on continuity as much as new features. - KoCoS is trying to protect installed customer workflows while improving portability and field usability. - Product Manager Jürgen Dreier said the PROMET SE+ is fully compatible with existing PROMET SE accessories, especially installed cable sets. - Dreier also said the compatibility lets users gain new functionality without replacing existing test equipment.

What's next: - Technical specifications and additional information are available on KoCoS' website. - The PROMET SE+ is positioned to slot into existing ACTAS-based test environments as customers upgrade field equipment. - KoCoS is likely to market the system as a lower-friction path for users who want mobile testing improvements without a full equipment replacement.

The bottom line: - KoCoS is updating a known resistance-testing platform with battery power, touchscreen control and backward compatibility to make mobile switchgear testing easier to deploy.
