Gaussmeter advise please
(1/1)
HighVoltage:
I am looking for a good Gaussmeter to measure the surface BR in mT of permanent magnets.
Any suggestion?
TERRA Operative:
Not sure how useful it will be seeing as I'm in Japan, but I'm currently getting a quote on a probe from AD-S here, so I know they are a source for meters and probes etc.

If I get a probe (absolutely no idea on cost yet...) I'll play with this meter I have for a bit, make a youtube video and probably be looking to sell it off in the next few months, if you are interested....?

I would look at Alphalabs for a basic Hall-probe based gaussmeter.

Another good distributor (at least in US) is https://gmw.com/product-category/magnetic-field-measurement/

Depending on how you want to approach this and how well your bench spare parts collection is you might consider a DIY meter.

I made one using the Allegro 1302 Hall effect sensor and a Motorola LP2951 voltage regulator.
Very inexpensive and quick to build. Almost rivals my lab unit for accuracy too.

I use it to measure ion pumps magnets. It will also detect the earth magnetic field well.
I mounted the Hall sensor at the end of a plastic straw with some heat shrink over. The readout is a voltage on my DMM.
