About This

• 3-in-1 EMF Meter for Different Signal Types - This emf meter measures three types of electromagnetic fields: Radio Frequency (RF) from wireless devices, Electric Field (EF) from wires and cords, and Magnetic Field (MF) from motors and appliances. Switch between modes to check signal levels around your home or office.
• Works with Common Wireless Devices - As a practical rf detector, it senses signals from everyday sources such as WiFi routers, mobile phones, Bluetooth devices, and smart home equipment. Provides real-time relative strength readings so you can see how signal levels change when you move closer or farther away.
• Visual & Audible Alerts with Portable Rechargeable Design - This emf reader features a tri-color LED (green/yellow/red) and an adjustable buzzer that alerts you when signal strength reaches different levels. Built-in rechargeable battery allows cordless use across multiple rooms or outdoors. Compact size fits in a bag or pocket.
• Simple One-Button Operation with Backlit LCD Display - This radiation detector is designed for easy use — press one button to turn on/off and switch modes. Large backlit LCD shows real-time numeric readings and bar graph levels clearly, even in low light. No complex setup, making it suitable for anyone curious about electromagnetic fields.
• Handy Tool for Learning About Your Environment - Use this emf detector to check different spots near a WiFi router, a running microwave, a phone, or other appliances. Its sensitive sensor responds quickly to changes, helping you learn where signals are stronger or weaker in your daily living and working spaces.
