Best Gauss Meter

To describe what is Gauss meter, one has to start from the Gauss’s unit. A Gauss is a standard magnetic field strength measurement unit named after Johann Carl Friedrich Gauss, the self-absorbed German mathematician and physicist.

Gauss units are equivalent to one maxwell per square centimeter. Gauss is the unit of magnetic field B, as per the alternative centimeter gram second system of units (cgs), while oersted is the standard for magnetic field H. A single tesla is equivalent to Gauss 104.

The Gauss meter functions to measure and calculate the value of Gauss. The units can be in Gauss (G), milliGauss (mG), milliTesla (mT), or microTesla (μT). Concerning the frequency of magnetic fields they are capable to calculate, Gauss meters differ. Higher efficiency handheld Gauss Meters, for instance, will scale from 0 to 30 kG with a reasonable precision of 1 percent.

Both static (DC) fixed (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs) are able to be identified by a gauss meter. Therefore, before making a decision, it’s important to take a look at your Gauss meter whether it’s able to measure both of them or not.

Top 10 Best Gauss Meters

1. Latnex Cornet ED-88TPlus

Latnex Cornet ED-88TPlus is actually an EMF meter. It’s able to measure RF radiation, electric field and surely magnetic field. Since it’s able to measure magnetic field strength, we include it here.

With a wide range of frequencies from 100 MHz to 8 GHz, the Cornet ED88TPlus is a reliable RF radiation detector. Besides, lower frequencies of electric fields ranging between 50 Hz to 50 kHz are also able to get recorded. As we are looking for a gauss meter, low-frequency magnetic fields varying from 50Hz to 10kHz can be measured with this device.

There are two different reading ranges you could select from. In order to get a greater resolution, surely you have to select the second range. It’s able to provide the resolution up to 0.1 mG.

  • Range 1: For the magnetic field from 50H – 10kHz, the reading range is 1 mG to 600 mG.
  • Range 1: The lower one, the magnetic field from 50 Hz to 1 kHz, the range is 0.1 mG to 10 mG.

When to Choose this One?

If you have to measure the magnetic field with several other tasks to measure like RF and other electromagnetic radiations, then this is a decent pick. However, this meter doesn’t provide a 3-axis mode. So, if accuracy is highly your priority, we don’t recommend this one.

Other benefits are the moving bar graphic and LED lights beside the screen. You could keep an eye on the moving graphic to monitor the radiation. The LED also gives you a quick alarm when the magnetic field radiation is out of a healthy level.

How Gauss Meter Works?

The Gauss meter operates by monitoring a current caused by a magnetic field that is emitted within the instrument by a loop of fine wire. The induced current is intensified by the circuits within the Gauss meter, causing it to calculate as minimal as 0.1 mg. Mostly on market, there will be two configurations available; a single axis coil or a triple axis coil. The single-axis is easier and, therefore, less costly. However, more detailed results are provided by the more complex triple axis meters.

Many Gauss meters arrive with automatic zero, peak hold, max/min hold, auto range, alert, storage hold, and comparative mode standard functions. Two modes also come from the probes: transverse and axial. Magnetic forces perpendicular to the probe axis is determined by the transverse probe. The axial electrode is placed perpendicular to the electrode axis by the Hall sensor and measures magnetic fields relative to the axis of the probe.

Gauss Meter Buying Guide

Since many Gauss meters are available online, so when reviewing specs and functionality to suit your needs, it’s easy to get confused. In this article, we have listed the ten best Gauss meters available on Amazon. But keep it in your mind that Amazon is not the only platform where Gauss meters are available. We have reviewed Amazon products just because it is considered as the best platform to purchase any item. While buying a Gauss meter, you should keep the following points in your mind:

  1. First of all, you should be aware of your need. Why are you buying a Gauss meter is very necessary for determining which device you should purchase. Most people purchase a Gauss meter to check the level of the magnetic field in their environment, electronic appliances, or home. The people who live near electric transmission lines mostly keep a Gauss meter to continuously monitor the magnetic field level around their surroundings.
  2. Whatever the reason is for which you are buying a Gauss meter, please check that if the Gauss meter is one-axis or 3-axis. A one-dimensional meter (1D) fitted with a single Hall sensor that calculates the flux density in one dimension is the simple variant. The 3D meter enables magnetic fields to be measured in free space. This gauss meter is fitted with three Hall sensors in 3 dimensions (x, y, and z) to calculate the flux intensity. So, if you are purchasing a Gauss meter for a very basic use then you should buy a 1axis Gauss meter. But if you want to measure magnetic field density more precisely then a 3-axis Gauss meter should be your choice.
  3. Another most important parameter to check, while buying a Gauss meter is the measuring range of the meter. The Gauss meters are available in various measuring ranges in the market. If your requirement is just household, and you don’t need a huge measuring range then you should buy a low measuring range Gauss meter, because it would be cheaper than the large measuring range meters.
  4. Also, check the resolution of the Gauss meter before buying. Likewise measuring range, the resolution of different meters is different. So, select that resolution which is suitable for you.

Conclusions

In this article, the ten best Gauss meters have been discussed. Their salient features alongside their pros and cons have been mentioned in the article. The axis of detection, resolution, and measuring range of different Gauss meters have been discussed. From the above-mentioned top 10  Gauss meters, the TM-192 3-Axis Gaussmeter is in our opinion the best Gauss meter. This is a three-axis Gauss meter. It can detect magnetic field intensity, electromagnetic field intensity, and electric field intensity. It also has a data logging function, which is very necessary for a Gauss meter.
