YINGHUA Back Probe Test Probe 2mm 0.7mm 71mm Red Black

SKU CH-PR30-HHHY5

A 0.7 mm diameter back probe with a 2 mm interface connects to a multimeter for 60 V, 10 A electrical testing

  • TypeVoltage Detectors
  • Fine 0.7 mm needle pierces insulation without cutting wires
  • 2 mm interface connects directly to multimeter or oscilloscope probes
  • 71 mm compact length reaches tight automotive and industrial test points
  • Red and black pair simplifies polarity identification during voltage checks
  • Rated for 60 V and 10 A to handle common low-voltage diagnostic tasks

Precision Back-Probe Set for Automotive Diagnostics

This pair of ultra-thin 0.7 mm steel needles fits a standard 2 mm multimeter interface and reaches 71 mm into tight connectors. They are built for technicians who need to pierce insulation without cutting wires during vehicle electrical work. The fine tips suit oscilloscope leads as well as handheld meters. Red and black colour coding keeps polarity clear.

Rated for 60 V and 10 A in Low-Voltage Circuits

The probes handle only circuits up to 60 volts and 10 amps, so they cannot be used on mains voltage or high-current starter systems. Their thin steel construction resists bending but will not survive accidental shorts on unfused battery feeds. Users must verify the circuit stays within these limits before connecting. No higher voltage or current rating is specified.

Push-On Installation With No Tools Required

Each probe slides onto a 2 mm banana plug in seconds; no soldering or screw terminals are involved. The snug friction fit stays secure during vibration but can loosen if the jack is worn or oversized. The hard needle point pierces most insulation cleanly, yet forcing it into thick or hardened sheathing can snap the tip. Inspect the tip after each use for deformation.

Questions about this item

Should I choose the red or black probe for my multimeter setup?

Both colours are included in the set; use red for positive and black for negative or ground connections when testing with a multimeter.

What does the 0.7 mm needle diameter mean when I am probing a live circuit?

The ultra-thin 0.7 mm steel needle can pierce insulation or packaging paper without cutting wires, allowing precise contact on small terminals.

How does the 2 mm interface affect what I can connect this probe to?

The 2 mm interface fits standard multimeter and oscilloscope test leads rated for up to 60 V and 10 A, capping the maximum voltage and current you can safely measure.
