2PCS Non Contact Voltage Tester Pen 24250V Sensitivity Electrical Detector Screwdriver with LED Light for Circuit Testing Description

Noncontact voltage tester pen set with two pens for safe, fast electrical checks. This compact tool detects live AC in wires, outlets, switches, and lamps without direct contact, and also provides a simple method for direct current checks. Two pens allow a backup or simultaneous work on different circuits for greater efficiency. Key benefits Safe, noncontact detection for AC circuits, reducing risk during troubleshooting. Twopen set offers redundancy or the ability to test multiple points at once. Compact and portable at 15.5 cm 6.10 inch length, easy to carry and store. Clear LED indicators and a selfcheck function for reliable operation before use. Features and specifications Measuring range: 24 to 250 V AC. Size: approximately 15.5 cm 6.10 inch in length. Probe tip diameter: 4 mm 0.16 inch. Probe exposed length: 17 mm 0.67 inch. Material: PC and HRA. Surface hardness / strong torque: 86 to 93 HRA. LED indicator behavior: green light shows the pen is working; no light indicates damage or battery replacement needed. Zero and live wire indication: live wire detection lights both red and green; zero wire detection shows green only. Direct current detection: hold the copper cap with one hand and the battery end with the other; a green light indicates sufficient electric power, no light means low or no power. Selfcheck function to confirm tester readiness before use. Practical applications Verify which outlet slots are live before replacing wall plates or installing devices. Check wiring at switches and junctions to identify live and neutral conductors during repairs. Test small batteries or lamp holders for DC presence using the direct current detection method.
