Accurate contactless voltage tester (12–300V AC) designed for safe, fast electrical troubleshooting Key benefits Precise voltage detection: Measures AC voltage from 12V to 300V, letting you verify whether a circuit is live without direct contact. Ideal for confirming power in automotive, appliance, and household circuits. Safer, non-contact testing: Contactless design reduces the risk of electrical shock by detecting voltage without touching wires or terminals. Useful when access is limited or when you want to avoid exposing live conductors. Clear digital display: The easy-to-read digital screen shows voltage levels and circuit status at a glance, speeding up diagnostics for both beginners and experienced technicians. Versatile and practical: Works across multiple applications—automotive wiring checks, home electrical outlet testing, appliance and fridge circuit inspections—so one tool covers many tasks. Portable and user-friendly: Handheld, compact form factor for convenient carry and use in tight spaces; straightforward operation suited to DIYers and professionals. What it solves Eliminates guesswork by clearly indicating whether a circuit is live, reducing time spent tracing faults. Lets you inspect hard-to-reach or enclosed wiring without exposing yourself to direct contact with live parts. Consolidates testing needs across vehicles, household systems, and appliances into a single, reliable tool. Typical use scenarios Automotive diagnosis: Quickly check whether a vehicle circuit is energized (12V systems) before replacing fuses or components. Home outlet and wiring checks: Verify whether wall outlets, switches, or junction boxes are live before starting repairs or installations. Appliance and fridge inspections: Detect live voltage in appliance circuits to narrow down faults without disassembling panels. Who should use it Mechanics and automotive technicians Electricians and maintenance professionals Homeowners and DIY enthusiasts performing routine electrical checks Performance and compatibility Voltage range: 12V to 300V AC (contactless detection) Function: Non-contact voltage detection with digital readout indicating voltage level and circuit status Compatible with: Automotive 12V systems, household AC outlets and wiring, appliances and refrigeration circuits Design: Compact, handheld tester for use in confined or hard-to-access areas A reliable, easy-to-use contactless voltage tester for accurate live-circuit detection across automotive, appliance, and household electrical work.
