Electromagnetic field meter WINTACT WT3122
Measurement of electric field (1–1999 V/m) and magnetic field (0.01–99.99 μT / 0.1–999.9 mG)
Built-in battery | Over-limit alarm | Temperature measurement

The Wintact WT3122 is a professional handheld tester of electromagnetic radiation fields – both electric and magnetic. The device is equipped with sensitive sensors and an LCD screen that displays real-time measurement values. Additionally, the meter warns about dangerous radiation levels using an LED indicator and an audible alarm.

The WT3122 meter can be used in homes, offices, industrial buildings, and outdoors – for monitoring the impact of electrical devices and power infrastructure.

Functions and advantages:

• Measurement of electric field (V/m) and magnetic field (μT / mG)

• Display of average and peak values (AVG / VPP)

• Warning alarm when exceeding permissible levels (over 40 V/m and 0.4 μT)

• Temperature measurement

• Backlit LCD screen

• Built-in lithium-ion rechargeable battery (USB charging)

• Compact and ergonomic soft-touch design

• HOLD function – freezes the measurement

• Selectable measurement units

Applications:

✅ Monitoring EM radiation in apartments, offices, industrial facilities, and outdoors
✅ Checking devices such as mobile phones, routers, computers, high-voltage cables, household appliances
✅ Evaluating the effectiveness of protective clothing, shielding foils, and other radiation protection measures
✅ Health and preventive measurements – especially for children, pregnant women, and seniors

Effects of EM radiation (according to WHO):

• May be one of the causes of leukemia in children

• Can lead to neurological disorders, tumor growth, cardiovascular diseases, and diabetes

• Disrupts the natural bioelectric field of the human body

• May cause vision impairment, immune disorders, and reproductive system problems
