DF-DIN TENSE Frequency Meter - True RMS

True RMS class frequency meter, particularly accurate for DIN rail installation.

The DF-DIN is designed to monitor the frequency range (from 1 Hz to 400 Hz) between phase to phase or phase to neutral conductor. The instrument is used to control frequency stability in single-phase and three-phase systems, which is particularly important for industrial equipment, generators, transformers, and power systems.

With a three-digit LED display, the frequency meter provides a clear and quick view of the data. The compact housing, easy installation, and high accuracy make the Tense DF-DIN the ideal solution for panel mounting.
