MR3 Milligauss Meter, Magnetoresistive for Static Magnetic Fields
The 3-axis MR3 Magnetoresistive Milligauss Meter measures and displays the three vector components (X, Y, Z) as well as the magnitude (M) of the static magnetic field (magnetic DC field).
Update is two times per second.
The three sensors are in a 25 mm (1") cube at the end of a flexible 100 cm (40") cable.
It can be powered by 4 AA batteries (included) or a worldwide AC adaptor (included).
It can collect and store data (X, Y, Z and M) for later download or stream data live via USB connector.
Both the instantaneous values of X, Y, Z and M, and their peak values, are displayed on the meter screen. "Peak" values are the highest values seen since the peak reset button was pressed.
Maximum error of sensitivity is ±0.5 % of the reading, and the maximum error of the offset is ±0.50 milligauss.
Range is ±1999.99 milligauss with resolution 0.01 milligauss (or 1 nT) over the full range, displayed simultaneously for X, Y, Z and M.
There is a "Zero" button which subtracts the instantaneous field for relative (tare) measurements, if required.
The instrument has a built-in datalogger that records X, Y, Z and M readings for a specified period of time. The data from the memory of the MR3 can later be downloaded into a PC via the USB interface, displayed as a spreadsheet or as measurement curves and also processed further by means of a spreadsheet software.
When connected to a PC via the USB interface and the free data logging software AlphaApp loaded, the data can be streamed in real time and stored to the hard disk of the PC.
There are two versions of the Milligauss Meter which differ in the accuracy of the sensor orientation (1° or 1/10°).
