MF-30K AC/DC Gauss Meter with Certificate, Measures Magnetic Fields Strength and Pole(Residual Magnet, Permanent). Integrated High AC ElectroMagnetic Fields Level Measurement (<15000G/Milli Tesla)

It works very well. measures from single Gauss up to 1Tesla (that's all the field I can generate in my work) you could just build one for less with a multimer and hall probe but this is convenient so get one. The product has one thing I'm worried about which is when you unplug the probe, there's a give there that I worry will become a problem but the meter works great.

More expensive than some other detectors out there but has a lot of versatility. I use it to find residual or unwanted magnetic fields around sensitive equipment. since the fields I look for are both EM and permanent it is nice to have one detector to find both as well as the strength of the fields. It is a niche tool but helpful when troubleshooting magnetically sensitive equipment. The digital thermometer built into the probe is nice to have as well.

It is a clean instrument that appears to be mostly correct.

I needed a tool to measure the magnetism surrounding very powerful magnets; their static magnetic fields. This was an advanced enough tool to do this precisely, with the potential to measure other fields as well.

The first unit was a failure, it did not work. Returned it and got a replacement. Hoping this one will not fail, so far so good. They said it's a new model for them. Their supplier should be scolded and told "this is a new model, test it thoroughly before releasing it" because it's a somewhat costly item, $400, so the expectation is not failing and having to return it.

Works as described, comes in a nice kit. I’ve only used it a few times but seems like a quality meter.

Received as promised. The instrument works as described. It might be useful to have additional information regarding orientation of the detector and details of the separation between the item under test and the detector. Overall it works well.

Worked well used it to calibrate rotors for pm motors. Amazing for inexpensive product.

Correu tudo bem. O aparelho funciona bem.

Work good, im not expert just aficionated.

All was OK with meter which I signed for.

It barely does the job for my application. For example, if the magnets are stacked together or are close to each other in some kind of assembly, then the device cannot measure correctly. The only way to measure is to take a magnet separately from the stack or assembly and make a measurement. This is very uncomfortable, especially in some kind of production environment where many measurements must be taken.

Works as it should, but the build quality is not good, typically made l china stuff. The connector for the sensor is very loose.
