Portable Electromagnetic Radiation Tester EMF Meter – Magnetic Field Detector with LED Level Display for Home & Office

Protect your living and working environment with the Portable Electromagnetic Radiation Tester EMF Meter – Magnetic Field Detector with LED Level Display for Home & Office.
This compact device helps you quickly detect and monitor electromagnetic radiation levels from everyday electronics such as Wi-Fi routers, TVs, microwaves, smartphones, power lines, computers, and household appliances.

Designed for simplicity and accuracy, the tester features a 5-stage LED level indicator showing radiation intensity from Safe to Danger Level, allowing you to interpret readings instantly without technical experience. Whether you're evaluating electronic safety at home, conducting field measurements, checking radiation-emitting devices, or performing professional inspections—this EMF meter delivers reliable results every time.

Key Features

• Dual-Mode Detection
  Measures both electric fields and magnetic fields at the same time for comprehensive EMF analysis.
• LED Visual Alert Display
  5-level LED indicators show readings at a glance — from Normal (green) to Extreme High Risk (red).
• Fast & Sensitive Measurement
  Detects EMF changes in real-time with a detection range of 0 – 20+ milliGauss (mG).
• Wide Application Use
  Suitable for testing household electronics, WiFi routers, mobile phones, microwave ovens, power lines, computers, smart meters, and industrial equipment.
• Battery-Powered Convenience
  Powered by a 9V battery (replaceable) with low-battery indicator warning.
• Portable & Lightweight Design
  Compact handheld build makes it easy to carry during inspections or field measurements.

Instructions 

1. Install the Battery: Open the battery compartment and insert a 9V battery (ensure correct polarity).
2. Power On the Device: Press the main power button once. The LEDs will flash briefly - this indicates the device is performing a self-check.
3. Hold the Meter Upright: Keep the device steady and avoid touching the sensor area while in use.
4. Point Toward the Suspected Source: Aim the sensor toward the device or area you want to measure, such as a router, microwave, power line, or electrical panel.
5. Read the LED Level:  Green lights (Safe), Yellow/Orange (Medium – caution recommended), & Red light (High radiation exposure – move away or reduce contact time). 
6. Move Slowly for Accuracy: If measuring a room or multiple devices, walk slowly and pause for 1–2 seconds at each location.
7. Rotate for Best Reading: Rotate the meter slightly - electromagnetic fields vary with angle. The highest number observed is the true reading.
8. Power Off After Use: Press the power button again to turn off and preserve battery life.

Maintenance & Safety Tips

• Do not use near strong magnetic interference or metal surfaces for long periods.
• Store in a dry location away from heat and moisture.
• Replace the battery when the low-power warning or dim LED indicators appear.
• Avoid dropping the device—internal sensors may become misaligned.

Invisible radiation is everywhere - from Wi-Fi routers and phones to microwaves and power cables. This EMF detector helps you instantly spot high-exposure areas so you can adjust device placement, reduce risk, and protect your space. Clear readings, fast results - peace of mind in seconds.
