Precise 3-48V DC Digital Readout

The Anyongora circuit tester pen delivers 0.1V resolution across a 3-48V DC range for accurate battery, alternator and fuse diagnosis on cars, trucks and hybrids. A clear LED digital display replaces dim incandescent bulbs so you can read exact voltage values at a glance.

Instant Dual-Colour Polarity Indicator

Red and green LEDs show positive and negative poles immediately without reading the numeric screen, preventing reverse wiring and short circuits during stereo or dash-cam installation. The bidirectional indicator simplifies every connection check.

Integrated Anti-Lost Probe Protection

A sliding guard keeps the stainless steel needle safe in toolboxes and prevents accidental stabs while reaching for the tool. The 96 inch spring wire stretches to eight feet for tail-light testing from the battery ground, and the backlit screen stays visible in dark footwells. DIYers needing AC measurement or data logging should choose a different instrument.

Questions about this item

How useful is the 0.1 V resolution when checking a 12 V car battery?

The 0.1 V resolution lets you see small voltage drops that indicate a weak cell or a failing alternator on a 12 V system.

What does the 3–48 V DC range cap in practice?

It covers 12 V and 24 V vehicle systems up to 48 V DC, so you can test cars, trucks and hybrids without exceeding the limit.

Will the 96 inch spring wire reach from the battery to the rear lights on a pickup?

The spring wire stretches to 96 inches, giving enough length to probe tail lights from the battery ground on most pickups.
