sensitive magnetometer (Speakesensor)
(OP)
I'm new to magnetic materials and I'm looking to acquire a magnetometer capable of detecting the presence of weakly magnetic materials, such as magnetite in its vicinity.
I've came across Foerster Magnetoscop 1.069, also discussed in this thread thread286-118604: QC of Magnetic Permeability of StainLess Steel but I think it's about $10,000 to buy.
I was just wondering if anyone has any experience with Speakesensor magnetometers http://www.speakesensors.com/ and whether or not this might do the same job for a fraction of the price? If so, are they relatively simple to set-up and use?
After contacting the manufacturer it seems the person who designed them, with all the technical knowledge, has sadly passed away but they still sell the sensors.
Thanks

RE: sensitive magnetometer (Speakesensor)
If you are trying to detect weakly ferromagnetic materials that are not magnetized then you need a very good controlled magnetic field. The Foerster is one of the best that I have ever used.
There are others but they are in the same price range.
They use very sensitive magnetometers in downhole drilling instrument packages. A bare circuit board about 2" x 6" with the electronics is about $20k, but they are meant to work hot also.

Do you know the advantages and/or disadvatages of using a single axis over a three axis magentometer for detecting weakly magnetised materials?

I can do absolutely anything. I'm an expert!

RE: sensitive magnetometer (Speakesensor)
If the samples re small or irregular shaped then a three axis unit will give you better results
