Voltage Detector for 50 to 1000V AC

The Amprobe VP-440 is a non-contact voltage detector designed for electricians and maintenance personnel who need to verify the presence of AC voltage. It operates across a range of 50 to 1000 volts and provides a visual light alert when voltage is detected. The probe tip allows for direct testing on conductors or terminals.

Verify CAT III 1000V rating and probe access

Before use, confirm that the electrical environment does not exceed the CAT III 1000V safety rating marked on the tool. Ensure the probe tip can physically reach the test point without requiring forced contact. This detector does not measure DC voltage and has no display for numerical readings.

Visual alert under continuous energised conditions

When held near a live AC source within the rated range, the indicator light activates immediately and remains illuminated as long as voltage is present. The response is consistent during sustained exposure to energised circuits. No flashlight is built in, so external lighting may be needed in dark locations.

Questions about this item

Does the Amprobe VP-440 come with batteries or a carrying case, or do I need to buy them separately?

The detector is supplied as a standalone unit; batteries and a carrying case are not included and must be purchased separately.

Should I choose the VP-440 or a model with a different voltage range for household wiring?

The VP-440 covers 50 to 1000 V AC, which matches standard household and light-commercial circuits, so it is the appropriate choice for that work.

What does the 1000 V CAT III rating mean when I am testing a live panel?

It means the probe is rated for measurements on fixed building installations up to 1000 V AC, providing protection against transient over-voltages in that environment.
