8103 Gauss Meter, Rechargeable Tesla Meter 0-2500mT, Magnetometer with Data Logging and Alarm, Magnetic Field Strength and Pole Tester, ±2% Industrial Accuracy for Quality Control, Labs

This 8103 Gauss Meter is a fantastic piece of kit. It delivers precise readings with excellent consistency and is perfect for both testing and calibration work. The ±1% accuracy gives real confidence in the results. Setup was quick and straightforward, and the rechargeable battery makes it convenient for regular use. The data logging function is a great bonus, allowing me to record and review measurements easily. The alarm feature is also handy when checking for field strength limits. Build quality feels solid and professional, and the display is clear and easy to read. Overall, an excellent, reliable, and accurate instrument that performs exactly as described. Well worth it.

Accurate

Well made test meter, certainly has the look/feel of a precision instrument as opposed to a 'cheap' gadget. It's very easy to use, with a clear readout of the results via a decent screen. The menu for various settings again is easy to navigate, and this is something you may want to look at straight away, in order to change the time-outs. The screen can be set to sleep from 1 to 9 minutes, and complete device shutdown from 1 to 9 hours. There is also a padlock symbol (for both options) that disables the timers. My meter had the (device) auto shutdown set to the padlock, meaning that although the screen had gone off after a few minutes, the device was still 'live', draining the battery of course. I only noticed this when I came to use the meter again the next day, and found the battery less than half full (despite an initial full charge-up before use). The sensor and strip looks rather delicate, so you'll have to be careful how you handle it and where you use it. I did a quick experiment by taking readings with the screw-on cover in place (the sensor in a fixed position with a magnet also fixed/static), and found negligible difference between the readings with or without it. This may be useful for certain jobs, if poking the probe in a location where it could be damaged for instance. The only things you'd have to do is mark the probe handle so you know the position/orientation of the sensor, and another (circle perhaps?) around the probe-cover to indicate the location of the sensor along its' length (actually about 16mm from the cover's tip when it's screwed on). The meter gives north/south orientation, so a simple experiment to find the poles of a bar magnet for example... as long as you position the sensor-side of the strip facing the ends of the magnet, you'll get the correct north/south reading. It's an impressive bit of kit, and whether you're using it for experimental or educational work, I don't think you'll be disappointed. Good stuff, and on a quality/value-for-money basis.... 5-Stars.

As an undergraduate I had to use a gauss meter in the practical laboratory. It was a very different device to the one offered here by AEGTest. However, it worked on the Hall Effect principle just like this model AEG-8103. When a current-carrying conductor is placed in a magnetic field, the magnetic field causes a voltage difference across the conductor. This, known as the Hall voltage, is proportional to the strength of the magnetic field. In use, the meter sends a test current through the probe which is attached to a lead. The Hall Effect produces a voltage that the meter records. This is displayed as the strength of the magnetic field, in units of Gauss (switchable to mTesla; 1 Tesla = 10,000 Gauss). The meter will also indicate the polarity of the field - either North or South pole. There are facilities to record readings, and sound an alarm if the strength of the magnetic field exceeds a user set value. This can be used in Quality Control testing. Information is displayed on a small but bright and clear screen. A short press of the on-off button brings up the menu page giving access to the different modes. The meter can be used to detect the regular passing of a magnetic field. It can count the number of events, and can calculate the number of events over a given time period and display as miles or kilometres an hour. Mostly, of course, this is employed by placing a magnet on a rotating shaft. This meter is a very neat hand-held unit. It is powered by an internal rechargeable battery via a USB-C port. A USB cable is provided but no charger. All is contained in a hard shell padded plastic storage box. There is a very comprehensive and readable manual provided. The one thing missing, at least I could not find it mentioned, is a facility for downloading results via the USB cable to a PC. Otherwise, this is a quite excellent meter.

In these days when school and college funding is short and lab equipment sparse, this Gauss meter is an excellent addition. It is well made, solid, with a good display. The probe is appreciably sensitive, and well protected in storage. However, it has proved rather tricky to fit it securely to the meter as it keeps falling off unless a few minutes are spent fitting and adjusting it on each occasion. We have been having a good deal of fun exploring the applications and limits of the meter. Firstly, it has a high degree of accuracy and therefore lives up to its description as being suitable for workshop applications. It withstands accidental thuds and knocks and rough handling by over-eager hands. The case is very robust and looks smart and professional.

Accurate and easy to read. It came with a carry case to keep the device safe and all accessories in one place. This is a very useful tool for both industrial and personal use. USB C rechargeable for added convenience too.

Handy bit of kit for anyone needing to measure magnetic fields without faffing about. The readings are consistent and the display is clear enough to interpret without any confusion. Adjusting settings is simple, and the response time is quick when taking measurements. The built-in alarm function is handy when needing to stay within specific ranges. Having the option to store data for later reference is a useful feature, especially when dealing with multiple readings. Battery life holds up well during extended use, so there’s no constant need to recharge. The included stand is convenient for hands-free operation, which is helpful when working on detailed tasks. A solid tool for those needing precise and reliable measurements.

Good quality and the screen is decent size. Ergonomic and the design is good as well. Came with the case which is a plus. Straight forward to use. Price is a bit on the high side.

The meter is responsive and easy to use, with a clear display that’s simple to read at a glance. Controls are intuitive and don’t require much reference to the manual, which makes it easy to get up and running quickly. Functionality is solid. Measurements update smoothly, and the telescopic Hall sensor is genuinely useful for reaching tight spots where a fixed probe would struggle. The size feels right for handheld use without being bulky, and it’s easy to carry around a bench.

I am scammed. The Device has no backlight. I has to take it out in the sun to see the numbers very faintly.

very useful for detecting strong magnets and polarity.

This is a fairly specialized tool, but if you need a gauss meter then you probably already know exactly why. A meter like this is useful for checking magnetic field strength, comparing magnets, looking for field drop-off with distance, checking equipment around motors or solenoids, or doing general electronics, lab, or quality-control work where guessing by feel is not good enough. For that sort of use this seems like a solid tool. It is not something most people need around the house, but it fills a real niche and is much more useful than trying to improvise with a phone app or some vague magnetic detector. I like that it is rechargeable, has a separate transverse probe, and includes features like data logging and an alarm, since those are the sort of practical details that make it more useful on a bench or in the field. Overall this is a good choice if you need to actually measure magnetic fields instead of just detect that one exists. It is a specialized instrument, but it feels like a real tool for that job. It feels very well made, and comes in a nice storage case with good foam inserts.

I have had this for a month, used it only a few times. The Battery will not hold a charge—it will charge to peak, and then drain after 5-20 minutes of use. Very obnoxious... Other than that, it reads Gs for my needs.
