## Long description

The Unit UT18C is a handheld non-contact voltage tester designed to detect the presence of AC voltage without physical contact. Rated for CATIII and CATIV environments, this compact tester identifies live conductors quickly and assists electricians and maintenance technicians with basic voltage checks, troubleshooting and safety verification in residential, commercial and industrial installations.
Advantages
The UT18C provides non-contact detection, reducing the need to expose conductors or disconnect circuits during preliminary inspections. Its CATIII/CATIV rating indicates suitability for use near distribution panels and service entrances, offering a level of protection appropriate for a range of electrical environments. The handheld form factor is lightweight and portable, enabling fast spot checks and visual indication of live conductors.
Suitable for
 Quick verification of live wires in residential wiring and outlets
 Routine maintenance checks in commercial electrical systems
 Safety checks near distribution panels and meter areas in industrial sites
 Troubleshooting faulted circuits and identifying energized conductors
Key specifications
 Function: Non-contact AC voltage detection
 Safety category: CATIII and CATIV rated for appropriate environments
 Form factor: Handheld, pen-style tester
 Primary use: Identification of live conductors and presence of AC voltage
How to use
Before use, visually inspect the tester for damage and ensure any required battery is installed and operational. Bring the sensing tip close to the insulation or conductor to be tested, without making electrical contact. Move the tester along the wire or near terminals; the device will indicate the presence of AC voltage according to its built-in visual and/or audible signals. Follow standard electrical safety procedures: de-energize circuits when required for hands-on work and use appropriate personal protective equipment.
Usage recommendations
Use the Unit UT18C as a preliminary check tool to detect energized conductors, not as the sole means of proving absence of voltage for safe work. Combine non-contact testing with proven verification methods and always follow local regulations and safety standards when performing electrical work.
