The GVDA GD189 meter is a 3-in-1 multifunction detection device that detects radio frequency (RF), electric fields (EF), and magnetic fields (MF). It features a built-in high-precision sensor for reliable measurements in various environments.

• RF Mode: Detects Wi-Fi signals, 5G networks (below 3.5GHz), and microwave radiation from household appliances.
• ELEC & MAG Modes: Measure electromagnetic radiation from televisions, induction cookers, refrigerators, computers, and power transmission lines.

The device features visual and audible alarms, with a triple backlit display and sound alerts. Numeric readings and trend graphs provide a clear picture of field strength.

It is easy to use and practical, equipped with MAX, Peak, and Data Hold functions. The 2.26-inch LCD screen is easy to read, while the device has an automatic power-off function for energy saving and a low battery indicator.
