Ecm Industries Llc GAT-3400 6V 12V Circuit Tester

Product Description

The ECM INDUSTRIES LLC GAT-3400 is a low-voltage circuit tester designed to detect voltage in 6-volt and 12-volt DC electrical systems. The tool features a sharp piercing tip that penetrates wire insulation without requiring the technician to strip conductors, and a 36-inch flexible lead that extends reach during testing. A 360-degree illuminated indicator provides clear visual confirmation of voltage presence. Electricians, automotive technicians, and HVAC service pros use this tester when diagnosing low-voltage control circuits, checking battery circuits, or tracing wiring faults in tight or hard-to-access locations.

The GAT-3400 is suited for residential and light commercial low-voltage wiring applications. Typical use cases include testing 6V and 12V DC control circuits in HVAC systems, automotive wiring, marine equipment, and similar low-voltage installations. The extended lead allows for safe, single-handed probing in confined panels and junction boxes. Package quantity is 5 units per order.

Key Features

• Tests voltage up to 12 VDC on 6V and 12V DC circuits
• Sharp piercing tip penetrates wire insulation without stripping
• 360-degree illuminated visual indicator for clear voltage confirmation
• 36-inch flexible lead for extended reach in confined spaces
• Compact, handheld form factor suited for field service use

Compatibility

Designed for use on 6-volt and 12-volt DC electrical circuits typical of low-voltage control wiring, automotive systems, and similar applications.

Installation Notes

This tool is used by licensed electricians, HVAC technicians, and other qualified trades for diagnostic purposes on low-voltage DC circuits. Always confirm the circuit voltage does not exceed 12 VDC before probing, as this tester is not rated for higher voltages. Follow applicable NEC guidelines and site safety procedures when working in energized panels or junction boxes.
