What is a magnetic field tester?

Electrical appliances and equipment produce electromagnetic emissions whenever they are put to use. EMF has been a key concern for people due to its ill effects. A magnetic field tester is a device that is designed to measure the amount of electromagnetic, magnetic, and electrical exposure that a device emits. The device measures low frequencies, static fields, and radiofrequency fields. The EMF exposure limit is set in different scenarios by industry regulatory bodies. Magnetic field testers or EMF detectors are used to measure these levels of EMF exposure and compare them with reference levels.

How does an EMF detector work?

EMF detectors are fitted with various sensitive components that can detect fluctuations in the magnetic and electrical energy in a particular area at any given point in time. The readings of this fluctuation enable users to detect the issues in the electrical wiring in the area and power lines. This method helps minimize EMF exposure and improve electrical infrastructure in manufacturing sites. With the increasing use of electronic devices, EMF exposure has grown tremendously, thus, the demand for EMD detectors has grown, too.

What is a normal EMF level?

The EMF levels are enforced at the national, local, and global levels by different organizations. On the global scale, the level of EMF is decided by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is an NGO recognized by the World Health Organization. In 2020, WHO published the ICNIRP guidelines on limiting the maximum EMF exposure from 100 kHz to 300 GHz.  In the US, the Environmental Protection Agency (EPA) regulates the EMF exposure recommendations by following the ICNIRP guidelines. In addition to this, various governmental agencies are also responsible for regulating the EMF exposure of different electronic equipment. For instance, the Federal Communications Commission (FCC) sets the limit of exposure for cell phones and cell phone towers, smart meters; EMF exposure regulation for nuclear power stations is regulated by multiple agencies including EPA, the U.S Nuclear Regulatory Commission (NRC), and the Federal Emergency Management Agency (FEMA), and workplace EMF exposure is regulated by the Health and Safety Authority (HSA).  
 

What are the precautions to take while using magnetic field meters?

Our EMF readers feature safety-centric designs, but you need to take the following precautions while using them.

• Read and fully understand the operating instructions before using it.
• Test the detector on a known live source before using it.
• Do not use the EMF meter if it appears to be tampered with or damaged.
• Do not use it to detect voltages higher than recommended.
• Always practice caution while measuring 30V AC and higher voltages.
• Replace the batteries if they show low battery indication.
• Use a soft dry cloth for cleaning the device.
• This instrument is designed for use in a pollution degree 2 environment.
