EMF Meter 30MHz-8GHz Three-Axis RF Radiation Detector

High-frequency EMF detection for home, office and field work

- This three-axis EMF Meter is designed to detect and quantify high-frequency electromagnetic fields from 30MHz to 8GHz. It helps you identify RF sources such as Wi‑Fi routers, mobile phones, base stations, Bluetooth devices and other wireless equipment, providing clear numerical feedback for assessments, troubleshooting and documentation.

The integrated three-axis (X, Y, Z) sensing probe measures fields in all spatial directions simultaneously, giving a more complete and reliable reading than single-axis meters that must be rotated or repositioned. The instrument supports multiple units, including V/m, µT, mG and µW/cm², with a maximum display value of 9999 and a sampling rate of approximately 0.4 seconds for responsive updates. A VA reverse-color display with both digital and analog bar indicators ensures readings remain easy to view in a range of lighting conditions. In addition to RF field strength, the meter also measures ambient temperature and humidity via a rear sensor with 12 air inlets, allowing you to capture basic environmental conditions alongside EMF data.

The device features an integrated 3.7V lithium battery and USB Type‑C charging (5V/1A), with an approximate charging time of 4 hours. An auto power‑off function (around 15 minutes) helps conserve battery during mobile inspections. Typical working conditions range from 0-50°C and 0-90% RH, with storage from -10-60°C and 0-80% RH. The meter is suitable for use in residential spaces, offices, industrial areas, power distribution rooms, transportation hubs, and near signal base stations or other RF installations. Package contents include: 1 x high-frequency radiation detector, 1 x instruction manual, 1 x USB Type‑C charging cable and 1 x storage bag.

Why It's a Smart Choice

• Three-axis RF sensing provides more complete and accurate field measurements without constant repositioning.
• Wide 30MHz-8GHz bandwidth covers common wireless technologies used in modern homes, offices and industrial sites.
• Clear VA display, temperature/humidity readout and rechargeable power make it practical for frequent professional or personal use.

FAQ

Q: What types of sources can this meter detect?
A: It is designed for high-frequency electromagnetic fields in the 30MHz-8GHz range, typically associated with Wi‑Fi, mobile networks, cordless phones, Bluetooth, RF transmitters and similar wireless equipment.

Q: Does it measure low-frequency fields from power lines or household wiring?
A: This model focuses on high-frequency RF radiation. For low-frequency magnetic fields from power systems, a separate specialized meter is generally recommended.

Q: How is the meter powered?
A: It uses a built-in 3.7V lithium battery and is charged via the included USB Type‑C cable using a 5V/1A power source.

Q: Can the meter be used for continuous monitoring?
A: It is suitable for repeated spot checks and short to medium measurement sessions. For unattended long-term logging, a dedicated monitoring system may be more appropriate.

Q: Is the display easy to read in different environments?
A: Yes. The VA reverse-color screen with digital values and analog bar indicators is designed for good visibility in typical indoor and field conditions.
