Digital EMF Detector with Backlight

This portable digital EMF detector measures electric field strength (1–1999 V/m), magnetic flux density (0.01–99.99 µT / 0.1–999.99 mG), and ambient temperature (0.1°C resolution). It uses a high-quality built-in electromagnetic sensor to ensure stable and repeatable results. The unit includes a backlit LCD screen, auto power-off after 5 minutes, data hold, averaging mode, and temperature measurement. Housed in sturdy black plastic, it is lightweight and ergonomic for extended handheld operation. Supplied as a single EMF tester unit only—no external batteries or cables included. Alarm thresholds are set at 40 V/m (electric) and 0.4 µT (magnetic), activating simultaneous audible beeps and LED alerts. A dedicated middle button allows manual toggle of sound output—ideal for quiet environments like bedrooms or offices. Its responsive interface and clear labelling make interpretation accessible even for first-time users. Designed for UK consumers evaluating typical residential exposures: testing near baby monitors, DECT phones, smart thermostats, underfloor heating controls, and external sources such as substations or overhead lines—supporting informed decisions about layout, shielding, or usage habits.
