The Multitec MT-100 Pocket Line Tester is an essential, high-quality safety tool designed for electricians, technicians, and DIY enthusiasts. Built to quickly and safely verify the presence of live Alternating Current (AC) in electrical circuits, this compact "test pen" is a must-have for every toolbox and workbench.
Available at Tomson Electronics, the MT-100 features a precision-engineered flat blade made from durable, nickel-plated alloy steel, allowing it to double as a light-duty screwdriver for terminal blocks and switches. The blade is housed within a fully insulated, high-grade transparent plastic handle that protects the user from electric shock. When the tip touches a live circuit and the user makes contact with the grounding cap, a bright internal neon lamp instantly illuminates, providing clear visual confirmation of voltage between 100V and 500V AC.

Q: How exactly do I use this line tester?
A: Hold the tester by the insulated plastic handle. Touch the flat metal tip directly to the bare wire or terminal you want to test. Then, place your thumb or finger against the metallic end cap at the very top of the handle. If the line is live, your body provides a safe, extremely high-resistance path to ground, which causes the neon bulb inside the handle to glow.
Q: Will I get shocked when touching the end cap?
A: No. The internal circuitry of the tester contains a very high-value resistor connected in series with the neon bulb. This limits the current passing through your body to a harmless, imperceptible level (usually less than a fraction of a milliamp).
Q: Can I use this to test my 12V or 24V DC battery circuits?
A: No. The MT-100 is a neon-based tester designed strictly for AC mains voltage (100V to 500V). It will not light up or detect low-voltage Direct Current (DC) from batteries or solar panels.
