Wera 247 SB Screwdriver Voltage Tester

The Wera 247 SB is a single-pole voltage tester designed to detect the presence of live voltage in the 100–250V range, making it an essential tool for electricians and electrical contractors working on domestic and commercial installations.

The Kraftform handle provides a comfortable, secure grip during use, while the sturdy clip allows the tester to be conveniently attached to a pocket or tool belt for quick access on site. The hexagonal body profile acts as an anti-roll feature, preventing the tester from rolling off surfaces when set down — a practical detail that helps avoid dropped tools and wasted time.

Ideal for checking sockets, switch lines, and consumer unit circuits, this phase tester is a reliable first-check tool before beginning electrical work. Its compact blade dimensions make it well suited for testing in confined terminal spaces and trunking.

Features and Benefits:
• Single-pole phase tester for voltage detection up to 250V
• Kraftform handle with integrated sturdy clip for pocket or belt attachment
• Hexagonal anti-roll profile prevents the tester rolling off work surfaces
