Electromagnetic Field Meter WT3120 Wintact
Measurement range: 1–1999 V/m | 0.01–99.99 μT | Frequency: 5 Hz – 3.5 GHz

The WINTACT WT3120 is a compact electromagnetic radiation tester designed to measure both electric fields (V/m) and magnetic fields (μT). The device allows quick and precise detection of radiation levels in the environment, indicating potentially hazardous values.

Equipped with a monochrome LCD screen, the meter continuously displays measurement results. An additional light signal (red LED) and an audible alarm function notify when the safe emission threshold is exceeded.

Applications:
✅ Measurement of radiation in homes, offices, and industrial facilities
✅ Checking emission levels from devices such as TVs, computers, routers, high-voltage lines
✅ Monitoring 5G radiation levels
✅ Testing the effectiveness of anti-radiation protection (clothing, films, shields)
✅ Health protection for sensitive individuals (children, pregnant women, elderly)
