Circuit Tester, 14cm, Chrome Vanadium, Orange, Premium LED Bulb Tester, Professional Auto Voltage Continuity Tester, Long Wire Probe

Circuit testers have a specified voltage range within which they can detect electrical voltage. This range may vary depending on the specific model and application, but commonly covers household voltages, Most circuit testers feature indicator lights, LEDs, or LCD displays that illuminate or display when voltage is detected in the circuit. These lights may vary in brightness or color to indicate the strength or polarity of the voltage., The probe tip of the circuit tester is designed to make contact with electrical terminals, wires, or components within the circuit being tested. It should be insulated to prevent electrical shocks and accidents., Many circuit testers feature long probe tips or extended probes to reach deep into electrical panels, outlets, switches, and other confined spaces where voltage needs to be checked., The handle of the circuit tester is insulated to protect the user from electrical shocks and ensure safety during use, especially when working with live circuits.
