Description. Product Description: An improvement on the flux gate magnetometer, the DC Milligauss Meter measures magnetic fields (technically flux density) up to several times the strength of the Earth field. It has a resolution of 0.01 milligauss (1 nanotesla) and a range of +/-2000 milligauss (200 microteslas).
What does a Gaussmeter do?
The modern version of the Gauss Magnetometer is known as a Gauss Meter. A Gauss Meter can measure the direction and the intensity of small (relatively) magnetic fields.One of the first devices that could be used for measuring the direction and strength of any magnetic field, was developed by him the magnetometer.
Is an EMF meter the same as a Gaussmeter?
An EMF meter can measure AC electromagnetic fields, which are usually emitted from man-made sources such as electrical wiring, while gaussmeters or magnetometers measure DC fields, which occur naturally in Earth’s geomagnetic field and are emitted from other sources where direct current is present.

How do you measure the strength of a magnetic field?
- Put a material in a magnetic field.
- Run a current through this material.
- The magnetic field will create a “sideways” change in electric potential across the material – which you can measure.
- Using this change in potential and the size of the material, you get the magnitude of the magnetic field.
How many Milligauss is safe?
2,000 milligauss
In its guidelines update in 2010, ICNIRP recommends a residential magnetic field exposure limit of 2,000 milligauss (mG) and an occupational exposure limit of 10,000 mG .
What is the least count of gauss meter?
The measurement range is from 0.01 mT (0.1 G or 0.01 kA/m) to 2.999T (29.99 kG or 2387 kA/m). The instrument is capable of measuring static (dc) magnetic fields and alternating (ac) fields.
What is a normal gauss reading?
What is a typical AC magnetic field level in a home? Inside a house usually measures about 0.2 to 1.0 mG if not very close to appliances or wiring. Apartments and condos are a bit higher. Beds and play areas can be located where the fields are low, for example below 1.0 mG.
How many gauss does a Tesla have?
10,000gauss
The SI unit for magnetic flux density is the tesla (symbol T), which corresponds to 10,000gauss.
What does a gauss meter read?
A gauss meter displays electromagnetic wave measurements in Gauss (G), milliGauss (mG), milliTesla (mT) or microTesla (µT) units. A gauss meter can detect either static (DC) permanent (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs), or both.
Who uses a gauss meter?
Gauss meters are useful devices, and an electrician who has one can diagnose miswired circuits more easily. In fact, a non-contact voltage tester detects electricity flow by the magnetic field it produces, so it is a type of gauss meter.
What does a magnetometer detect?
4 Magnetometer. A magnetometer is a scientific instrument used to measure the strength and direction of the magnetic field in the vicinity of the instrument.
How do you calibrate a gauss meter?
Calibration is obtained by using a Zero Gauss chamber and a magnet with a known flux density value. It is important to note that this method obtains a flux density reading in Gauss (Tesla) which is not the same as the Gauss (Tesla) number specified as the Intrinsic Residual Induction, Br.
What causes the needle of a compass to spin in a circle?
A magnet is what makes a compass point north the small magnetic pin in a compass is suspended so that it can spin freely inside its casing and respond to our planet’s magnetism.
How do you measure electromagnetic radiation in your home?
You can check EMF levels in your home with an EMF meter. These handheld devices can be purchased online. But be aware that most can’t measure EMFs of very high frequencies, and their accuracy is generally low, so their efficacy is limited. You can also call your local power company to schedule an on-site reading.
What is the difference between magnetic north and true north?
True north is a fixed point on the globe.Magnetic north is the direction that a compass needle points to as it aligns with the Earth’s magnetic field. What is interesting is that the magnetic North Pole shifts and changes over time in response to changes in the Earth’s magnetic core. It is not a fixed point.
What is considered a high EMF reading?
Summary: Electric field readings within living spaces above 10 V/m (Volts per meter) are considered high. Dangerous levels of electric field radiation are talked about much less than magnetic field and radio frequency radiation.
Is 2 milligauss safe?
However a growing body of articles and studies suggests that there may be health risks at EMF levels as low as 2 milligauss, probably depending on many variables including length of exposure in the field, actual field strength during the exposure period, person’s age, body mass, general health and perhaps genetic
What is acceptable EMF level?
Magnetic fields for occupational exposures should be limited to less than 0.5 mT (5 gauss or 5,000 mG). Should I be worried about my exposure to EMF? The scientific information which exists doesn’t indicate that exposure levels which are commonly encountered have any health effect which requires corrective action.
How is gauss measure?
One gauss corresponds to the magnetic flux density that will induce an electromotive force of one abvolt (10–8 volt) in each linear centimetre of a wire moving laterally at one centimetre per second at right angles to a magnetic flux. One gauss corresponds to 10–4 tesla (T), the International System Unit.
What is digital Gauss meter?
Digital Gauss meter works on the principle of Hall Effect in semiconductor. When a semiconductor with current flowing in one direction is introduced perpendicular to a magnetic field a voltage is produced at right angles to the current path.This Hall voltage is amplified and calibrated as magnetic field.
