DF-DIN TENSE Frequency Meter - True RMS

Highly accurate True RMS class frequency meter, DIN rail mounted.

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

The three-digit LED display provides clear and fast data readings. Thanks to its compact housing, easy installation, and high accuracy, the Tense DF-DIN is an optimal solution for panel mounting.
