Model 245

Circuit Sniffer

The Model 245 is a compact, short-range interference locator designed specifically for indoor RFI troubleshooting. It accelerates the process of identifying noisy circuits and sparking devices by eliminating the need to repeatedly switch breakers on and off. Built for utility technicians, RF specialists, and facility engineers, the 245 provides fast, localized detection of broadband interference affecting radio, television, and low-band communications.

Indoor noise complaints often originate from small appliances, lighting controls, and electronic power systems. Traditionally, isolating these sources required shutting down individual circuits and resetting customer equipment. The Model 245 streamlines this process by allowing technicians to pinpoint the source circuit at the meter or breaker panel, then identify the offending device using high- and low-frequency antenna modes.

By combining a directional probe, dual-frequency antenna, and LED signal-level meter, the Model 245 delivers a fast, reliable workflow for locating indoor RFI in homes, offices, and industrial facilities. Its sensitivity, rugged construction, and intuitive controls make it a practical tool for resolving interference complaints efficiently.
