  • 2 mm interface plugs straight into standard multimeter leads
  • Red and black pair simplifies polarity identification

What these probes do

YINGHUA back-puncture test probes have a 0.7 mm needle that slides into insulated wire without stripping. The 2 mm banana plugs fit standard multimeter sockets. Rated for 60 V and 10 A, they suit automotive maintenance, electrical testing and industrial troubleshooting. Each set includes one red and one black probe in the short 43 mm style.

Deciding specification

The 0.7 mm needle diameter is the figure that determines whether the probe can reach the conductor inside thin automotive or sensor wiring without damaging surrounding insulation. If the target wire gauge or insulation thickness demands a thicker or longer tip, this short-style probe will not make reliable contact. Choose the long or curved variant when deeper reach is required.

Installation and common issues

Push the 2 mm plugs into the multimeter until they seat firmly, then press the needle tip through the insulation at the test point. The most frequent problem is the fine tip bending or breaking if forced against a hard conductor or pulled sideways; always align the probe axially and use minimal pressure. Verify the multimeter range stays within 60 V and 10 A before each measurement.

Questions about this item

How does the 0.7 mm probe tip perform when back-probing a live circuit?

The 0.7 mm diameter tip is designed for back-puncture testing, allowing precise contact with insulated wires without damaging surrounding insulation during automotive or electrical diagnostics.

What does the 2 mm interface limit when connecting to a multimeter?

The 2 mm banana plug interface fits standard multimeter inputs rated for 60 V and 10 A, capping the maximum measurable voltage and current to those values for safe operation.

Will the 43 mm short body fit inside a crowded fuse box?

At 43 mm long, the short-style probe body is compact enough to manoeuvre in tight automotive fuse boxes and dense industrial panels where longer probes cannot reach.
