Features: Compact, lightweight, and portable with a built-in high-accuracy chip, making it practical and easy to use. Features a clear-definition color screen with colorful font design, capable of performing well in various environments to provide a comfortable user experience. Simultaneously detects three parameters: RF intensity, electric field intensity, and magnetic field intensity. Data is displayed on the same interface, indicating whether each measurement meets standard criteria. Equipped with a radiation level grading function—three different colors correspond to different radiation levels, enabling a clear and visual understanding of the current environment. Includes a sound alarm that activates when detected levels exceed safe thresholds, with a mute button to disable the alarm sound. Multifunctional design with a lock screen (data hold) feature and support for displaying maximum and average values. Suitable for multiple applications and can be widely used in kitchens, near high-voltage equipment, homes, offices, factories, and more.
