Product Details

This instrument features high detection sensitivity, wide sample capacitance coverage, broad applicability, complete input unit (detection impedance) configurations, and multiple frequency band combinations (9 types). After proper calibration, it directly reads discharge pulse magnitude with simultaneous pointer and digital display. The pointer display conveniently switches between logarithmic and linear scales. It is a practical PD Tester widely used by power utilities, manufacturers and research institutions.
