RDINSCOS EMF Meter Rechargeable Electromagnetic Field Radiation Detector Hand-held EMF Reader Tester with Sound and Backlit Alarms EMF Monitor for EF RF MF, WiFi, Microwave and Ghost Hunting

Accurate Measurement: The EMF meter can detect three types of electromagnetic radiation: electromagnetic field (EF), magnetic field (MF) and radio frequency field (RF)

Double Alarm:When the EMF measurement exceeds (250 V/m or 5 μT/50 mG or 50 mW/m²), the unit sounds an audible alarm and the screen turns red. The buzzer can also be turned off as required to avoid disturbing ghosts

EMF reader:Large backlit LCD screen can clearly display the measured value. Test average or peak (maximum), press HOLD to save data for viewing

Function Upgrade:In EF mode, display AC frequency; MF mode, capable of detecting X/Y/Z three-axis magnetic field radiation; It can also recognize three types of radio frequency radiation (RF): WIFI/PHONE, MICROWAVE, and MIXED. The units can be switched

Why use an EMF detector: It can help measure electromagnetic fields, identify devices that cause high-level radiation, and enable users to make informed decisions. It is suitable for radiation applications such as home use, outdoor activities, and ghost hunting

User friendly:The RD637 ghost tester is easy and convenient to operate. It has a charging function and can come with a charging cable. In addition, in APO mode, the device will automatically shut down after 15 minutes of inactivity to extend battery life
