Hantek HT8100 High Voltage Isolated Probe

Description

The Hantek HT8100 is a high-voltage differential probe designed for safely measuring floating and high-energy circuits with an oscilloscope. With 100 MHz bandwidth, strong common-mode rejection, and dual attenuation ranges, it’s ideal for power electronics, motor drives, and SMPS debugging where standard probes simply aren’t safe or suitable.
