502 Frequency Counter/Generator


The Model 502 Frequency Counter/Generator has been designed to generate and measure AC wave forms used in process and control applications such as jointless track circuit signaling for the railroad industry. It is ideally suited for testing and calibrating equipment that measures or displays industrial rate parameters such as RPM, FPM, GPM and 2500 Hz Audio-frequency overlay rail signals.

Housed in a light-weight, high-impact plastic case, the Model 502 is hand-held and field portable.
