DC-XXB DC Spark Testers

The DC-XXB is ideal for very high-speed applications, testing multiple-conductors, heavy loads, or very delicate insulation such as foam. The DC-XXB meets a variety of common industrial specifications including UL 2556, UL 1581, and IEC 62230 (when properly applied and using an application appropriate electrode).
