Extech MF100 - AC/DC Magnetic Field Meter - Hall Effect Sensor with Automatic Temperature Compensation

Es un buen equipo, hace lo que tiene que hacer, pero el usuario debe saber que el campo magnético es un vector, entonces la medida depende de la dirección del sensor.

I did not expect this little device to be so good. It is comparing very well with tools 10x more expensive. We are using it to check the magnetic field in large beam deflecting magnets and it works very well. The probe is indeed great. The technology really got better in this domain.

this meter does not read anything near reality. I borrowed an NIST calibrated meter to test against because I was suspicious - everything is 2.6 G no matter where I point the probe. Yep, its readings are bs. This meter is nothing more than an expensive prop. Do not buy.

Very good all around meter, easy to use.
