Corn Electronics Dual-Range Voltage Tester

The Corn Electronics voltage tester is a non-contact AC detector built for electricians and DIY users who need to identify live or null wires quickly. It covers two measurement spans, 12 V to 1000 V and 48 V to 1000 V, with selectable sensitivity modes. Visual and audible alarms indicate voltage presence and wire type. The tool meets IEC CAT III 1000 V and CAT IV 600 V safety ratings.

Before Use Checks

Verify that the circuits you intend to test fall within the stated AC voltage ranges of 12 V to 1000 V or 48 V to 1000 V. Confirm the tester’s CAT III 1000 V and CAT IV 600 V ratings suit the installation category of your work environment. Ensure a fresh battery is fitted; a low-battery icon appears on the LCD when replacement is needed. The device operates only on AC voltage, so it cannot be used for DC systems.

Bundled Features Impact

The integrated LED flashlight illuminates dim work areas without requiring a separate torch. Adjustable sensitivity lets you switch between low and high modes to distinguish between standard and low-voltage conductors. Live-wire detection triggers a rapid buzzer and continuous red tip illumination, while null-wire detection produces a slow alarm with a green LCD. Both modes provide immediate on-tool feedback.

Questions about this item

Does the tester come with a battery or do I need to buy one separately?

The tester includes a battery; a low-battery icon appears on the LCD when replacement is needed.

When should I use the 12V-1000V range versus the 48V-1000V range?

Use 12V-1000V for high-sensitivity detection down to 12V AC; use 48V-1000V for standard-sensitivity work where voltages start at 48V AC.

What does the CAT III 1000V and CAT IV 600V rating mean for daily use?

It certifies the tester for safe measurements on fixed installations up to 1000V and on supply-level circuits up to 600V.
