The EL AC digital frequency meter is a round panel-mount instrument that shows the live frequency of the connected AC supply on a bright red digital readout. The 35-99Hz range covers both 50Hz and 60Hz mains systems plus the lower and upper extremes used in generators and inverters.

The Φ22 cut-out matches standard pilot-light openings, making it easy to retrofit into existing control panels. The compact body (Φ22 diameter, 4.70cm height) keeps depth requirements behind the panel reasonable, and the durable construction is rated for long-running industrial duty.
