10 Best Emf Detector of September 2025

• Detects all three types of EMF pollution: AC magnetic, AC electric, and RF/microwave
• Peak Hold captures fast pulses, for measuring fast digital signals
• 3-axis AC magnetic field, 1-axis AC electric field, 1-axis RF (reads all existing 5G, etc.)
• Fast indicator bar quickly shows hot spots, and adjustable backlight
• 1-Year Manufacturer Warranty

TriField

• ▲EMF Meter Function - Testing the magnetic field for home use mainly.
• ▲Measure Radiation - of TV, induction cooker, rice cooker, refrigerator, computer, for low-frequency home appliances, electrical wires, etc.
• ▲Sound-light Alarm * When the test result exceeds the safe value, the instrument will alarm automatically.
• ▲Data Hold & Max Measurement - One-key lock the radiation value.
• ▲Large & Clear LCD Display - of the values for easy reading.

Meterk

• ▲NO RF DETECTOR - The EMF tester has more uses than other's tester, testing the magnetic field radiation with optional units mg/µt, the electric field with unit v/m and ambient temperature with 2 units ℃/℉. More uses in the EMF tester can help you check out whether the place is radiation-free and constant temperature; but it can't detect RF value directly
• ▲ONLY FOR ELECTRIC DEVICE - The detected data can be locked and the maximum data can be locked at the same time. LCD display can be turned on and off, and there is a flashlight and hole for connecting the tripod on the back of the tester
• ▲LARGER FREQUENCY RANGE - The measurement frequency range is larger up to 5HZ—3500MHz, getting more accurate measurement of daily home appliances: TV, mobile phones, computer, induction cooker, refrigerator, electrical wires, etc
• ▲SOUND-LIGHT INDICATOR - When the test result exceeds the safe value(> 4.0 mG / > 0.4µT/> 40 V/M), EMF tester will alarm with sound and light. The sound frequency of the alarm will be stronger and the light is turned red from green as the increase of radiation value
• ▲WHAT YOU GET - 1 x EMF Meter, 1 x 9V Battery, 1 x User manual (Just contact us or send it back for a full refund, our customer service will solve it in time)
