Voltage Indicator Unit UT12S-EU CAT IV 1000V IP67, non-contact voltage tester

The Unit UT12S-EU non-contact voltage indicator detects presence of AC voltage up to CAT IV 1000V. Its pen-style form factor and compact size allow quick one-handed checks on cables, outlets, switches and junctions without direct contact. The housing is rated IP67 for dust- and water-resistance, making the tester suitable for outdoor and industrial environments. Visual and audible alerts provide clear indication of live conductors, while a simple tip-based sensing area enables fast verification of energized circuits.

Advantages

The tester combines high overvoltage protection classification with a rugged IP67 enclosure to support safer checks in demanding sites. Non-contact operation eliminates the need to expose live parts, reducing risk during voltage detection. Dual-mode indication—bright LED and audible beep—improves visibility in noisy or poorly lit conditions. Battery-powered, lightweight construction and pen-style clip offer portability for electricians and maintenance technicians who require frequent, rapid checks.

Suitable for

• Quick live-voltage checks on power cables and conductors
• Testing wall outlets, switches and junction boxes without contact
• Routine maintenance inspections in industrial and outdoor settings
• Use by electricians, installers and field service technicians

Key specifications

• Detection type: non-contact AC voltage sensing
• Voltage range: suitable for systems up to 1000 V AC (CAT IV rating)
• Protection class: overvoltage category CAT IV
• Ingress protection: IP67 dust- and water-resistant enclosure
• Indicators: visual LED and audible buzzer for presence of voltage
• Form factor: compact pen-style housing with pocket clip
• Power: battery-powered operation for portable use

How to use

Hold the tester by its insulated body and bring the sensing tip close to the conductor, outlet or switch you want to check. Observe the LED indicator and listen for the audible signal to confirm presence of AC voltage. Keep fingers behind the insulated grip and avoid direct contact with exposed live parts. Follow standard lockout–tagout and safety procedures before performing any work on electrical installations. Replace batteries when indication becomes weak or intermittent to ensure reliable operation.

Usage recommendations

Use the indicator for preliminary voltage checks only; do not rely on it as the sole means to verify absence of voltage when performing electrical work. For precise measurements and troubleshooting, use a rated multimeter or contact-based tester. Store and transport the unit in a dry place and inspect the housing before use to ensure IP67 integrity.
