Digital Gaussmeter/Tesla Meter Magnetic Field Tester

This is another of those items that either works as advertised or doesn't, and this one does. We used it to test, and it showed the same results as a unit borrowed from a friend. It's accurate, as far as we can tell, and it's easy to operate. Pros: We found no flaws on the one we tested. This works as advertised, with no issues. Results matched a unit from a friend, indicating it's likely accurate, since both are not likely to be wrong and giving the same results. Cons: None that I've found. Overall, based on our testing, this is a good option and worthy of your consideration. Good luck finding what will work for your needs.

Okay. The first impression of the appearance is that this meter which is made of plastic doesn’t look fancy like some other more expensive one. To be honest, I think looking cheap has more to do with color choices than material choice. Regardless, this one does its job well on measuring the intensity and direction of relatively small magnetic fields in my opinion and I think that should be the only thing that matters. (still, come on, this one is at least $60 more expensive than the one that looks just like this except the cheaper ones come with protruding buttons. … Anyway, I am sure some people are interested in this product because of guitar pickups. While other factors affect the tone of pickups, the magnetic strength of material does so to a great extent. So many people I know compile the gauss level of many different pickups and obviously if you are building the pickup yourself, it is important that you have this type of tester to know the gauss level of the one you are making to ensure its tone. In my opinion, it takes real patience to measure it to build your own. Based on my experience with using it (only) for guitar pickups, I would say this one is quite a good one, but might not be the most cost effective one however. (Just because the same model with a very similar looking Gaussmeter is being sold at a much cheaper price). Still, if you are looking for a Gaussmeter because you want one to measure pickups to ensure that it is at the optimum level for the design, this one will be perfect for your purpose.

Great little Gaussmeter Tesla Meter Surface Magnetic Field Tester with N/S Function + Metal Probe. I like the probe. I recommend my friend. I hope you always win. Thank you. God bless you. If this was helpful for you, please check helpful. Below. May the rest of your life, be the best of your life. OZ

I own several mechanical magnetometers by R B Annis. This instrument came with a case for protection for the meter and probe. Instruments such as this not that long ago were very expensive. Easy to toggle between the standards. Uses 4 AA batteries which i see as a long life of this meter as opposed to a non user replaceable battery. A real pluse using the meter with the probe.

This is a neat toy. Tests the polarity and amount of magnetism work well. I'm just a hobbyist playing around, but I can see that this would be useful for scientists and engineers as well.

The build quality is really lacking for this Gaussmeter. I suppose there isn't a huge amount of competition for devices like these, but it's a really dated chassis next to even the cheapest multi-meters that get cranked out of China. The included instructions are a joke of bad English and typos. For $144, I do expect a little bit of proof-reading, or even a basic spell-check. The figures are pretty bad too. In particular, one part is trying to warn you not to bend the probe, or you'll break it... but if you don't read it carefully, you'd think it's trying to tell you that you should bend it to use. The meter is functional, it works well at detecting magnetic fields, and behaved largely as I would expect next to different types of magnets... I can't check accuracy though. There's no calibration documentation, just a QC tag in the case. The case is 9.625 x 8.25 x 2.8 inches in dimensions. The whole thing takes 4x AA batteries (included), but can also take a 6V 1A power supply, terminated with a standard 3.5 x 1.35mm barrel plug with positive center (included power supply has a 3 foot long cord). The probe is just under 2.25 inches long, and should definitely be protected from damage. The probe cable is about 30 inches long, and terminates at a right angle - I've included a picture of the connector so you might be able to use replacement probes with the same connector.

I cannot say anything bad about this unit. It appears to work exactly as advertised and operationally, the buttons make sense. The carrying case is typical foam inside a hard plastic shell. All gaussmeter/magnetic field tester probes are delicate enough that you have to be careful with them so having a case is a good idea. The issue I have with this unit is you would have a hard time spending more money on a handheld gaussmeter that does only what this unit does. Another way of saying it is you can spend half as much money and get the same functional performance from a different unit. Therefore this unit gets a low price-to-performance rating. Again, there is otherwise nothing wrong with the unit. But if you shop around, you will see what I mean about price-to-performance ratio. 3 stars.

Good low cost meter for quick checks.
