Overview
The Taparia Multipurpose Digital Line Tester / Voltage Detector (Model: MDTN-82) is a compact 130mm diagnostic tool equipped with a digital LCD display for precise direct and non-contact voltage testing. Engineered for electrical contractors and maintenance technicians, it safely detects AC and DC voltages from 12V to 250V and features an inductive mode for tracing cable breakpoints and electromagnetic fields.
1. Core Engineering Features
- Digital LCD Readout Screen: Provides clear, immediate numerical voltage indication and mode verification, offering superior precision over traditional neon-bulb testers.
- Dual Direct & Inductive Test Modes: Supports direct contact testing for AC/DC voltages (12V to 250V range) alongside a non-contact inductive mode for detecting high-voltage fields, radiation, and hidden cable faults.
- Durable Transparent ABS Housing: Built from high-impact transparent plastic to withstand rigorous jobsite use while incorporating an integrated pocket clip for easy transport.
- Dual-Touch Operation Terminals: Features dedicated conductive rear contact touch points that allow users to switch seamlessly between direct measurement and induction breakpoint scanning.
2. What’s Included in the Box
- 1 x Taparia Multipurpose Digital Line Tester / Voltage Detector (Model: MDTN-82)
3. Primary Use Cases
- Live wire identification, phase checking, and neutral or earth line verification in electrical panels
- AC and DC voltage measurement across a 12V to 250V operating spectrum
- Tracing hidden cable breaks, faulty wiring runs, and live electrical fields behind walls without stripping insulation
4. TK Tools Pro-Tip
When performing direct voltage tests, ensure your finger makes solid contact with the metal terminal at the top of the tester handle to complete the circuit for an accurate LCD readout. Switch to the inductive mode and run the tip along insulated cables to quickly locate hidden breaks or pinched wires behind drywall!
