Quick response: The voltage circuit tester is equipped with a sensitive indicator light. Once the voltage is detected, the quick response indicator will promptly send out a reminder, which can prevent false results and accidental injuries, and it is safer and more accurate to use Strong versatility: The test range of this car volt circuit test pen is 6V to 24V, which is the most common voltage range on the market. It can help test the motorcycle trunk or any other electronic equipment in the car. A 96 cm long wire can help you detect difficult-to-reach equipment, which is quite practical Portable design: The circuit test probe is about 17.8cm long, and the probe is about 8.5cm long. It has an accurate length for accurate automotive voltage testing. The compact size makes it easy to carry and easy to use. This is an unmissable product, very suitable for you to use High quality: The handle of the car-borne voltage circuit tester is made of high-quality AS material, which is super hard, strong, not easy to break, electric resistance, high heat resistance, and safe to use. The probe is made of hardened and tempered chrome-plated carbon steel, rust-proof and very sharp, and can easily penetrate the wire insulation to check the circuit. High quality, easy to use for a long time, worth buying Specification: Material: AS plastic, Carbon steel Handle Color: As the picture show Pen Length: 17.3cm / 6.8inch Probe Length: 8.3cm / 3.3inch Line Length: 96cm / 37.8inch Package Weight: 118g Quantity: 1pc Clamp Capacity: 20 AMP Bulb: 3 Watt Bulb (Replaceable) Voltage Range: 6V-24V
