GVDA GD189 Electromagnetic Field Radiation Meter

GVDA GD189 Electromagnetic Field Radiation Meter is a modern device designed to measure electromagnetic radiation levels in electric, magnetic, and radiofrequency fields. It uses a built-in sensor and microprocessor to deliver accurate results displayed on a clear digital LCD screen. The meter supports 3-axis magnetic field measurement, allowing reliable detection in any direction, and offers a wide measuring range including 0.01-200.0 μT for magnetic fields, 1-2000 V/m for electric fields, and 0.001-100.0 mW/m² for radiofrequency radiation. It includes functions such as peak value detection, data hold, color backlight indication for different radiation levels, and automatic sound-and-light alarms when safety thresholds are exceeded. The display also provides an analog bar and trend graph for easier interpretation. The device is energy-efficient thanks to automatic shutdown after 15 minutes and a low-battery indicator. Made from durable ABS, it operates within 0-40°C and 40-80% humidit
