8103 Gauss Meter, Rechargeable Tesla Meter 0-2500mT, Magnetometer with Data Logging and Alarm, Magnetic Field Strength and Pole Tester, ±5% General Accuracy for Factories, Workshops

Works as advertised, easy to use and accurate.

This is a very good instrument for the price point. I'm working on a passion project in spintronics. This meter is incredible for under $100.

It's not every day we reach for a Gauss meter, but when certification time rolls around (looking at you, FCC!), suddenly knowing your magnetic fields from your elbow becomes mission critical. We usually lean on the testing houses to do the heavy lifting, but as any engineer will tell you, it's always nice to walk into an exam knowing you've done your homework. That's where the AEG-8103 Gauss Meter steps up and delivers.With its ±5% accuracy, it's plenty precise enough for pre-certification checks, troubleshooting motors, or simply verifying you're in the right ballpark before handing things over to the pros. It measures magnetic field strength (Gs/mT), checks pole direction (handy for those Monday mornings when you're not sure which way is north), and even has nifty QC and counting/speed measurement modes.Build quality gets two thumbs up - solid feel, snug connections, and it all comes neatly packed in a padded, rugged carrying case. For us, this case is a lifesaver since the meter spends most of its life perched on a shelf between gigs, protected and labeled clearly (in big friendly letters: GAUSS METER!) so we don’t have to scramble around when the certifying deadline looms.Battery life? Nailed it. This thing sports a rechargeable 750mAh Li-ion battery topped off via USB-C (welcome to the future, folks!). Even after a few months of shelf-hibernation, it's always juiced and ready for action - and if we've forgotten to plug it in, no worries - it charges up quick right out of the gate.One last nice touch: the manual is superb - clear as a summer morning and available in multiple languages. No more Google Translate sessions when the pressure's on.Summary:This Gauss meter earns its keep by giving us solid confidence when certification day comes. If you occasionally play hide-and-seek with magnetic fields, you'll be glad you have this tucked away on the shelf.Pros:✅ Solid 5% accuracy (great for pre-certification checks)✅ Robust, padded carrying case keeps it safe and organized✅ Rechargeable Li-ion battery via USB-C (always ready to go)✅ Clear, multilingual manual✅ Intuitive interface with helpful QC and speed measurement modesCons:❌ Wish the testing cable was just a tad longer (minor nitpick)🏅 Verdict:Magnetic fields beware - this meter's charged, cased, and shelf-labeled to perfection. A solid confidence booster in our certification prep arsenal.

I’ve used this Gauss meter to test the field strength on some permanent magnets from an old project, and the color display gives a clear reading of both the intensity and the polarity. The live graph showing the field strength as I move the probe closer is a useful visual. While I don't have a way to formally test its calibration, I did notice that returning the probe to the same spot on a magnet gives very repeatable readings, which is a good sign of its consistency. The whole kit, including the probe and charging cable, fits into a standard carrying case, and the meter itself is rechargeable via a Type C cable.The device has some interesting secondary functions. It can measure rotation speed by counting changes in a magnetic field, which I tried out on a small DC motor; it provided a steady RPM reading. For hands free work, like if I needed to log data over time, the built in stand on the back allows it to sit upright on my workbench.

This seems like a good tool to have around the house, especially when I charge my EV at home. I did a test on my Tesla, when it’s not being charged, bd while it’s charging. The reading did increase while it’s being charged. Especially in the undercarriage area. Which kind of make sense, since all the batteries are located in that area. I am not an expert on using a gauss meter, but nice to have this round to get some readings when needed.

There are many exciting features included in this meter. It looks to be well coveted already so I’ll just briefly mention my favorites.One, its ability to detect minute changes in the magnetic field near the probe. It can tell polarity as well as its strength, which is nicely plotted on a running scale. I have no way to confirm its precision but I give no reason to doubt its tolerance that’s listed.Two, and oddly enough, it can be used as a device to measure rotation. It counts the number of times the magnetic field changes and can give you a reliable speed or RPM of the device under measure.It comes in a standard carrying case and happily, is rechargeable. You would thing just about anything electronic these days would be but some are not. Fortunately, this is.Anyway, I’m sure there are industrial uses for this but where I see it bringing the most joy would be to that upcoming science major, who can’t get enough physics and electricity in their lives. I would have loved something like this when I was a young nerd instead of an old nerd.

While this meter isn't going to get used every day, when you need it...well, you need it. I was immediately impressed with the build quality and especially the carrying case, which is very robustly designed and offers excellent padding for the meter, probe, and so on. The manual is very well written and readable--at least the English version, anyway! It's also printed in 5 other languages, none of which I'm qualified to read and evaluate.As far as the functioning of the meter goes, it worked very well once I figured out how to position the Hall sensor. It's helpful at identifying the polarity of a magnet, and its accuracy is well within my needs. There's a very interesting mode available where the meter will count RPMs (how often a magnet attached to a wheel passes by the meter) and even more interesting was an additional capability of being able to enter the circumference of the wheel in use and having the meter tell me the speed (in MPH or KPH) that the wheel is turning.All in all this is a great device if you need to measure magnetism.
