DF-DIN TENSE Frequency Meter - True RMS

Highly accurate True RMS frequency meter for DIN rail mounting.

DF-DIN is designed to monitor the frequency range (from 1 Hz to 400 Hz) between phase and phase or phase and neutral wire. The instrument 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.

With a three-digit LED display, the frequency meter provides clear and quick data visualization. The compact housing, simple installation, and high accuracy make the Tense DF-DIN an optimal solution for panel mounting.
