HF-15B High Frequency Spark Tester

The HF-15B is ideal for applications testing smaller wires at high line speeds or when a direct ground to the center conductor is not possible/practical. The HF-15B meets a variety of common industrial standards including UL 2556, UL 1581, and IEC 62230 (when properly applied, using an application appropriate electrode.)
