The Triplett ET350 Non-Contact Voltage and Magnetic Field Detector is a compact, professional electrical testing tool designed for electricians, HVAC technicians, low-voltage installers, maintenance personnel, and service contractors. Combining a non-contact AC voltage detector with magnetic field detection capability, the ET350 provides fast and safe identification of energized circuits and magnetic fields without direct metal-to-metal contact.

Designed specifically for US applications, the Triplett ET350 features dual AC voltage detection ranges with enhanced sensitivity optimized for 120V systems. The low-voltage detection capability allows technicians to identify wiring commonly found in thermostats, doorbell circuits, control systems, and video surveillance camera power wiring. With magnetic field detection for AC, DC, and permanent magnets, along with a built-in flashlight and CAT IV 1000V safety rating, the ET350 is a versatile tool for electrical troubleshooting and installation work.
