High Torque Electrician Tester Screwdriver - Smart Breakpoint Phillips Tool

Experience precision and reliability with the High Torque Electrician Tester Screwdriver, a versatile multi-function tool designed for both professionals and DIY enthusiasts. Constructed with a CRV alloy steel tip, this tool combines durability with top-tier performance, ensuring it withstands the rigors of daily use.

The device features a measurement range of 70-250V for contact tests and up to 600V for non-contact measurements, allowing you to accurately diagnose electrical issues with ease. It also includes a through-circuit check capability up to 20 megohms, a polarity test for 3-36VDC, and a voltage test range of 50-500Hz.

Measuring approximately 163 x 24 x 4 mm, with a tip diameter of 4 mm, this tool is compact and easy to handle. It operates on three 1.5V LR41 button batteries, which provide reliable power for extended use.

Key functional features include an insulated shell that is drop-proof and durable, ensuring safety during operation. The intelligent upgraded motherboard chip enhances performance and longevity. This dual-use electrical pen combines the functions of an electrician pen and screwdriver, featuring a strong magnetic tip for secure fastening and voltage sensing capabilities to identify live wires quickly.

The bright and sensitive color lights offer clear visual indicators for safe power measurement, with red and green lights signaling different circuit conditions—both lights illuminate for live wires, while only green lights up for the neutral zero line.

A self-test function ensures that the device is in proper working condition. When activated, the tester emits a bright light, confirming its readiness for use. If it fails to light up, this indicates the need for battery replacement.

Additionally, the line break detection feature allows for the rapid identification of circuit failures. By holding one end of the tool while testing another wire, a green light confirms a complete circuit, while the absence of light points to a break.

For DC power detection, simply position the tip against the positive terminal of a battery while touching the negative terminal with your hand. A lit indicator signifies sufficient power, while a dark indicator means the battery may be depleted.

With its intelligent design and comprehensive functionality, this electrician tester screwdriver is a reliable choice for accurate electrical measurements and diagnostics.
