The LATNEX AF-3500 Multi-Field EMF Meter is a Semi-professional but small and compact device that can measure electromagnetic field (3-axis), electric field, and RF strength. The AF-3500 measures high-frequency electromagnetic fields (RF) in a frequency range of 50MHz - 3.5GHz and low frequency electric and magnetic fields (EMF) at 50-60Hz.

Magnetic field strength is measured in milliGauss (mG) and microTesla (μT) for 3 axis X, Y, and Z.

Electric field strength is measured in volt per meter (V/m).

RF field strength is measured in millivolt per meter (mV/m).

A 2 inch color TFT LCD screen displays the 3 results clearly all at the same time, with also the option to hold the 3 results.

Who Utilizes an EMF Meter?

EMF meters empower individuals to make informed decisions about managing their exposure to different types of electromagnetic fields for their personal well-being.

  1.  Workplace Safety: EMF meters are often used in industrial settings to assess the levels of EMF radiation around machinery, equipment, and power lines, ensuring compliance with safety regulations.
  2. Environmental Monitoring: EMF meters can be used to assess the levels of EMF radiation in specific environments, such as residential areas, schools, hospitals, and public spaces.This can help identify potential exposure concerns.

  3. Health Concerns: Individuals who are concerned about electromagnetic hypersensitivity (EHS) can use EMF meters to measure radiation levels in their living spaces and make adjustments to reduce exposure.

Applications for EMF Assessment and Use

Discover diverse applications of EMF meters: assessing radiation from cell towers, devices like cell phones, smart meters, and transformers, ensuring workplace safety, monitoring environmental exposure, and addressing health concerns. These tools play a crucial role in understanding and managing electromagnetic fields.

RF Mode: Detects Signals Emitted Wirelessly by Various Devices

Microwave Ovens

Measure the radiation leakage from microwave ovens.

WiFi Modems

Measure the radiofrequency radiation emitted by WiFi modems, routers, and Bluetooth devices. This can help individuals optimize the placement of these devices to minimize exposure.

Cell Phones

Measure the radiation emitted by cell phones or Cordless phones. This can help individuals choose cell phones with lower radiation levels or adopt safer usage habits.

Smart Meters

Smart meters used for electricity, gas, and water monitoring emit electromagnetic radiation. EMF meters can measure the radiation levels near smart meters and help people understand their exposure.

Cordless Phones

Cordless phones emit electromagnetic radiation, especially when in use. EMF meters can be used to measure the radiation levels from cordless phones and encourage safer usage habits.

MF and EF Mode: Functions as a Gaussmeter, Detecting Magnetic and Electric Fields from Different Sources

Electrical Wires

Measure the magnetic fields generated by electrical wires, transformers, and other electrical equipment. This is useful for identifying areas with high levels of magnetic fields, which could impact human health or interfere with sensitive equipment.

Solar Panels

Solar panels and associated equipment can produce electromagnetic fields. EMF meters can be used to assess the levels of electromagnetic radiation in the vicinity of solar panel installations.

Electronic Devices

Measure the electromagnetic radiation emitted by various electronic devices, such as Tv's, laptops, tablets, and desktop computers.

High Power Lines

EMF Readings from High-Voltage Power Lines.
