Precision Frequency Monitoring for Your Electrical Panels

Maintaining a stable AC frequency is critical for the health of your sensitive electronics and heavy machinery. This Square Digital AC Frequency Panel Meter provides real-time, continuous tracking from 0 to 99Hz. Designed for seamless integration into automation systems, generators, and distribution boxes, it removes the guesswork from power monitoring.

Crystal Clear White LED Readout

Visibility is paramount in busy machine rooms or dimly lit workshops. The meter is equipped with an ultra-bright, 3-digit white LED display. This ensures that your electrical frequency data cuts through the glare and darkness, giving you an immediate and accurate reading without needing to open the panel.

Engineered for Safety and Durability

Built to withstand demanding environments, this digital Hz indicator features a multi-layer protective structure. The included rubber sealing ring and top protective cap guard against dust and moisture ingress at the panel front. Internally, the specialized ventilation slots ensure efficient heat dissipation, keeping the internal components cool even during continuous, round-the-clock operation.

Effortless Installation

Time is money when assembling control cabinets. This meter features a standard cylindrical body designed for easy panel mounting, secured by a durable locking nut. The bottom base is equipped with standard X1 and X2 screw terminals, allowing for fast, secure, and solder-free wiring. Just strip, insert, and tighten.
