Features: Item: QD-102A Neon-lamp Test Pen, Single-pole voltage tester, 100V to 500V AC/DC, 140mm
The one contact neon lamp voltage tester usually have the form of a screwdriver, it's a simple piece of electronic test equipment used to determine the presence or absence of an electric voltage.
Screwdriver test pen is a low-cost type of test lamp, let the tip of the tester contacts one side of the circuit under test, and rely on stray capacitance and current passing through the user's body to complete the circuit. Because a neon lamp takes very little current to light, so we can use the user's body capacitance to earth ground to complete the circuit.
DQ produce voltage tester pen out of several materials with different appearance design according to global customer requirements for more than 25 years.
A resistant plastic is used for the core which ensures that the blade is held securely even under high strain.
We aslo develop balck coated manufacturing technique to increase the hardness of a blade, which provides high frictional resistance and allows the application of high forces.
