72x72 mm Digital Frequency Meter (1-400 Hz) (15 V - 500 V AC)

The DJ-F72 is a digital frequency meter designed for the precise measurement of frequency in electrical systems . It allows for continuous monitoring of the network frequency, ensuring reliable control of the electrical system.
The device measures the frequency from the input voltage (phase-to-neutral or phase-to-phase) and displays the value clearly and immediately on its digital display. It is easy to operate, with an LED status indicator.
Thanks to its compact panel-mount design, the DJ-F72 integrates easily into electrical panels, making it ideal for industrial and energy control applications.
