Product Highlights
- ✔️ ️safe and reliable: this easy to hold and ergonomic pen-style voltage finder signals the detection of voltage through the illumination of a glowing red led situated within the tip as well as a clear audible tone for a dual feedback response.
- ✔️ built in led torch: complete with a handy built-in flashlight, the labgear voltage detector is perfect for illuminating dark work areas especially in harder to reach areas so you can see what you are doing without external light sources
- ✔️ ️ac voltage detection: the labgear voltage detector pen is a quick and simple method for non-contact detection of the presence of ac voltages from 90v to 600v with improved balance sensitivity for more accurate detection
- ️✔️ multi purpose: ideal for use in identifying the presence of ac voltage at socket outlets, switches, circuit breakers, fuses, luminaries, wires and cables. it can identify breaks in conductors by tracing along the cable from the source to the point where the indicator no longer illuminates; and also identify a blown fuse while in circuit.
- ✔️ a brand you can trust: founded in 1932, labgear are a proudly british company designing and manufacturing high quality products used by professionals. labgear also has an enviable reputation for innovation, quality, reliability and excellent customer service.

Product Highlights
- Ncv induction: the breakpoint finder has an ncv sense probe for ac voltage, just place the tip near an outlet or power cord. you know voltage is present when the red light turns on and the pen beeps.
- Automatic shutdown: the electrical tester is double insulated for safety and complies with ce standards. when the battery voltage is lower than 2.5v, the power indicator will light up; it will automatically shut down after 5 minutes of no operation or no signal detection.
- Safety first: when the detected voltage is higher, or the closer it is to the voltage source, it will beep at a higher frequency and the light will be red. red means high voltage and live wires are detected, yellow means low voltage and neutral wires are detected.
- Dual range: detects standard voltages and low voltages (12-1000v ac / 48-1000v ac) for more sensitive and flexible measurements. press the h/l key to adjust sensitivity to accommodate low ranges for doorbells, thermostats, irrigation wiring, etc.
- Compact design: the voltage tester features a bright led flashlight for working in dim locations; pocket-sized pen hooks allow you to carry it in your shirt pocket.(laser: class 2, maximum laser output <1mw)
