FieldSentry Sensors, Display and Alerts

Three-Axis Sensing

Three sensors sit perpendicular to each other inside the housing. Each one reads a different axis of a field, so the meter picks up readings however you hold or turn it.

Field Types Covered

The meter reads magnetic fields, electric fields and RF signals at once. That lets you check household wiring, appliances and wireless sources with one handheld tool.

FieldSentry

Color-Coded Alerts

Alerts are color coded and paired with a buzzer. When a reading crosses the threshold set in the meter, the color changes and the buzzer sounds so you can mark the spot.

LCD and Controls

A clear LCD display shows live readings as you move. Simple one-button controls keep operation basic, so you can start scanning without reading a long set of instructions.

Frequently Asked Questions

It reads magnetic fields, electric fields and RF signals. The RF mode covers wireless network and cell signals, including 5G frequencies, so one meter handles wiring, appliances and wireless sources.

Live values appear on the LCD display. Color-coded alerts and a buzzer add a second signal when a reading crosses the threshold built into the meter, so you can glance down or just listen.

No. The controls are simple and use one button, and the LCD display shows readings directly. The instruction manual in the box covers the basics if you want a reference while scanning.

It runs on a charge and has an automatic shutdown feature for when you stop scanning. Check the instruction manual for charging details before first use.

Hold it in whichever way is comfortable. The three perpendicular sensors read all axes, so orientation does not need to be exact. Move slowly through the space and watch the display.

Each sensor faces a different axis. Together they read a field from all directions at once, instead of depending on a single sensor being lined up with the source.

The meter is ready to scan once powered on. There are no setup steps listed beyond reading the instruction manual and, if needed, charging it.

You get the FieldSentry EMF meter, an instruction manual and a storage bag. Keep the meter in the bag between uses so the display stays clean and the unit is easy to carry.

An EMF meter measures magnetic fields, electric fields, and RF fields. FieldSentry reads all three at once with three internal sensors and displays live values on its LCD.

The EMF reader has an LCD display for live readings plus color-coded alerts and buzzer warnings. Controls are simple, with one-button operation, and the unit arrives pre-calibrated.

FieldSentry: A Three-Axis EMF Meter for Home and Workshop Scans

FieldSentry is an EMF meter for home and garage scans, built around three perpendicular sensors that read magnetic, electric, and RF fields together. The sensors sit on separate axes, so the unit reads fields from whatever angle it is held.

As an electromagnetic field meter, it shows live readings on an LCD display while the user walks through a room, garage, or workshop. Color-coded alerts and buzzer warnings mark readings that cross a known threshold.

People use this EMF reader to check appliances, chargers, and wireless or cellular sources, or as a general EMF detector and EMF tester around the home. It arrives pre-calibrated, and one-button controls keep operation simple.

  • Three-axis sensing for magnetic, electric, and RF
  • EMF meter LCD display with live readings
  • Color-coded alerts with buzzer warnings
  • Manual and protective storage bag included
