Overview
The Ywcking C4 EMF Radiation Detector is a compact, high-sensitivity instrument designed to accurately measure electromagnetic fields in both residential and industrial environments. Equipped with a professional-grade sensor and intelligent chip, it provides real-time radiation analysis across magnetic and electric field ranges, displayed clearly on a vivid digital LCD screen.
This detector offers dual measurement units including mG/µT for magnetic fields and V/m for electric fields, enabling lab-level precision for diverse applications. It features real-time and peak value modes, allowing users to switch between continuous monitoring and capturing maximum exposure levels.
Designed for practical use, the C4 incorporates smart threshold alerts with triple warnings when EMF levels exceed safe limits. Users can mute the audible alarm while keeping visual indicators active, making it suitable for sensitive environments.
Its USB-C rechargeable battery, auto-sleep function, and lightweight design make it ideal for home safety checks, workplace EMF assessments, ghost hunting, and outdoor investigations. Backed by a 3-year warranty and lifetime support, the Ywcking C4 combines accuracy, ease of use, and durability in one device.

FAQs
Does this detector measure both magnetic and electric fields?
Yes, it measures magnetic fields in µT/mG and electric fields in V/m with separate sensors.
Can it detect RF radiation like WiFi or 5G signals?
No, it does not measure high-frequency RF radiation. It is designed for magnetic and electric field detection.
How does the alarm system work?
The device triggers a red screen, LED flash, and buzzer when readings exceed 40 V/m or 0.4 µT.
Is it suitable for ghost hunting?
Yes, its sensitivity and real-time response make it useful for paranormal EMF investigations.
How is the battery charged?
It includes a USB-C cable for recharging the built-in lithium battery.
Can the sound alarm be turned off?
Yes, long-pressing the AVG/VPP button mutes the sound while keeping visual alerts active.
Does it retain readings when turned off?
No, readings reset after power-off, but data can be held temporarily with the HOLD function.
