Go Direct® 3-Axis Magnetic Field Sensor, order code GDX-3MG, $69
Specifications and User Guide
- Primary Test: Press the power button on the sensor to turn it on. (The red LED will flash.) Start the Graphical Analysis app on your device and select the sensor from the list of available sensors. (The green LED will flash to indicate the sensor is connected.) Move the sensor near a permanent magnet and check for the magnetic field readings to change.

-Maximum wireless range: 30 m, unobstructed
-Overall length (handle + shaft): 19.5 cm
-Shaft: length 12.2 cm, cross section is square with slight taper. Maximum cross section is square, 9 mm x 9 mm closest to the handle.
-Handle dimensions: length 7.3 cm, maximum width 3.3 cm
Go Direct 3-Axis Magnetic Field uses Bluetooth low energy technology and can only be used wirelessly with devices that support Bluetooth low energy technology running the appropriate software. Otherwise, connect the sensor to your device using the included USB cable.
This sensor requires Graphical Analysis 4 software on iOS, Android, Chrome, Windows, or macOS.
-Calibrate? No. The sensor is set to the stored calibration before shipping.
-It is not practical to calibrate the Magnetic Field Sensor without reference to a known source of magnetic field. It is useful, however, to zero the Magnetic Field Sensor. Position the sensor, and zero it using the data-collection software. Then, move the magnetic field source (but not the sensor) to explore the spatial variations of the field.
