KAIWEETS KEMF-1 EMF Radiation Detector, EF/MF/RF Data, LED Display, Type-C Charging Port

High-Precision Measurement

Three display areas simultaneously measure electric fields (V/m), magnetic fields (µT/mG), and microwaves (mW/m²), helping you monitor electromagnetic radiation levels in real time. You can also use the EMF detector for fun "ghost hunting" activities.

Smart Design

The electric field and microwave monitoring are uniaxial—point the top of the device at the measurement area for more precise data. The magnetic field monitoring is triaxial, allowing detection in any direction. Equipped with a Type-C charging port for convenient recharging anytime.

Wide Frequency Range

Detects electromagnetic radiation from household appliances, mobile phones, WiFi, transformers, and more. Measurement ranges: RF Radiation: 0.001–200 mW/m²; Magnetic Field: 0.01–200 µT / 0.1–2000mG; Electric Field: 1–2000 V/m.

Intelligent Alarm Reminder

When radiation levels exceed safety standards, the device automatically emits an audible and visual alarm to help you quickly identify potential risks. A silent mode button allows you to toggle the alarm on or off as needed.

Portable & Easy to Use

Features a large high-definition LED display. The function buttons let you adjust the main display and measurement units freely. With a smartphone-sized design, it is easy to carry for on-the-go detection.
