Electromagnetic Field Meter

As the name already describes, magnetic field meters are used in industry and research to measure a magnetic field. It does not matter whether the magnetic field measuring device measures a static (DC) magnetic field or an alternating (AC) magnetic field. Magnetic field meters for static magnetic fields are used to determine the field strength of the permanent magnets. The magnetic field testers can also measure the field strength of the AC fields under certain conditions. Magnetic field meters for alternating magnetic fields, i.e. electromagnetic fields, are defined by the frequency range that the magnetic field measuring device covers.

For measurements of electromagnetic fields from power lines, substations etc. the magnetic field meters covering a frequency range at 50/60 Hz are used. Often, though, the magnetic field meters are used, which can measure a wider frequency range. For example, magnetic field testers are used that are suitable for electromagnetic fields between 30… 300 Hz. In the AC magnetic field meters, internal measuring coils, similar to antennas, are often used to measure an electromagnetic field. Here the magnetic field meters are divided into two groups: uniaxial and triaxial measuring probes. Magnetic field meters with a 3D measuring sensor are much easier to use. In the magnetic field meter itself there is a possibility to switch between the X, Y and Z axes. In practice, this makes handling easier. When using magnetic field measuring devices with one measuring probe, it is necessary to pay attention that the measuring device is always correctly aligned with the magnetic field, otherwise the measuring device cannot reliably measure the electromagnetic radiation. In contrast, this type of magnetic field meter is comparatively cheaper. Both types of the measuring devices can be found in the products range of PCE Instruments.

Magnetic field testers for static magnetic fields are used to measure the field strength of magnets. Magnetic field measuring devices of this type use a Hall sensor to determine the magnetic strength. The Hall sensor is able to precisely determine the field strength. Thus, the magnetic field measuring device can not only measure the strength of the magnetic field but also detect the direction. The magnetic field meter for DC fields is also able to determine the north and south poles. Magnetic fields of this type are often also called Gauss meters.

Electromagnetic field (EMF) has become widely popular in recent years as many individuals are showing interest in knowing just how strong an EMF field is within the home or office. There are many common electrical appliances found within the home including radios, computers, microwave ovens, telephones, and iPads where the presence of EMF fields are quite high.

An electromagnetic field meter is designed to detect and characterize the strength of an emission. This ensures that safety measures are taken when limits are exceeded in order to maintain favorable conditions. The application of an electromagnetic field meter will allow you to detect the exact source of an extremely high emission, as this may otherwise be difficult to determine without any auxiliary help. Many of today’s devices are found within close range of each other, creating a dense, highly concentrated electromagnetic field. This meter will also detect sources that may be hidden within the area, helping to solve the implicit problems.

The activity of the emission is dependent upon the usage of each device and because the EMF is not a stable magnitude, it may change within a short amount of time. It is important to know the strengths and levels of an EMF as this gives an indication about how safe the atmosphere is within a certain environment. Making simple changes such as moving the source of emission to another corner or enlarging the distance between the devices can have positive effects including a reduction in the value of emission. This change or reduction can be verified with the help of a electromagnetic field meter.

Establishing a comfortable and healthy living environment without the potential hazards of high electromagnetic levels can be done easily and conveniently with an electromagnetic field meter. This easy to use meter is designed for new users who are not familiar with the features of EMF and its formation, but who have concerns about their well-being and having the ability to maintain a healthy living environment.
