The SpinMeter-Ultra-3D is a low noise 3-axis USB fluxgate magnetometer with a frequency response from DC to above 1kHz. The calibrated sensitivity and temperature coefficient of sensitivity with linear output make the SpinMeter-Ultra-3D ideal for precision compassing, high sensitivity field mapping, and discrete low noise field measurements. With a resolution of 15 nT and a full scale range up to ±1000 μT, the SpinMeter-Ultra-3D is suitable for a wide range of applications.

The SpinMeter-Ultra-3D can be used with or without a PC. Analog outputs are always active provided a suitable USB power supply is connected to the mini-USB type B input.

The SpinMeter-Ultra-3D comes with a 3-axis magnetometer, an amplifier, cables and software.
