FieldSentinel Sensors and Display

Three-Axis Sensing

Three sensors work together to compute the peak reading, so the way you hold the unit matters less. The detector covers magnetic, electric and RF field types.

Backlit LCD Readout

A large backlit LCD shows the live reading for the mode you have selected. You can check values on appliances, cables and wireless sources in a dim room.

Color and Buzzer Alerts

A three-color backlight changes with the reading level, and an audible buzzer sounds alongside it. You can follow the signal without reading every number on the screen.

Simple Controls

One button switches between modes. The unit is pre-calibrated and comes with an instruction manual, so you can unbox it and begin scanning rooms and devices.

FieldSentinel: An Electromagnetic Field Detector for Home and Shop

FieldSentinel is an electromagnetic field detector for garages, workshops, and home offices where wiring, chargers, and wireless gear sit close together. Three sensors read magnetic, electric, and RF fields in the same scan, in any orientation.

Used as an EMF meter, it shows live values on a large backlit LCD and marks readings with a three-color backlight and a buzzer. One button switches modes. Live readings update on screen as the unit moves through a room.

Pointed at appliances, extension cords, routers, or tool chargers, this EMF detector doubles as an EMF reader for each field type, from one handheld unit. The electromagnetic field detector arrives pre-calibrated.

  • Triple-axis sensing for magnetic, electric, and RF fields
  • Large backlit LCD display
  • Color backlight with audible buzzer
  • Protective carry pouch and instruction manual included
