Pocket voltage tester for electricians and DIY users

The NCVT1P is a non-contact AC voltage tester pen designed for professionals and homeowners who need to verify live circuits without direct contact. It detects voltage from 50 to 1000 volts AC in cables, breakers, lighting fixtures, switches and standard outlets. Two AAA batteries and instructions are included in the box.

Compact CAT IV 1000V housing with pocket clip

The rectangular body measures 5.5 by 0.72 by 1 inches and weighs .05 pounds, making it easy to carry in a shirt pocket. A bright green LED confirms the tester is operational, while a flashing red LED and audible beep alert when voltage is present. Auto power-off conserves battery life, and the housing is rated for a 6.6 foot drop. The CAT IV 1000V safety rating covers industrial and utility environments.

50 to 1000 volt AC detection range

This single specification defines the tester’s suitability: it will not indicate voltage below 50 volts AC, so it is not for low-voltage control circuits, automotive systems or tamper-resistant outlets that require a lower threshold. Measurement accuracy is stated at 98 percent.
