The QuSpin Total-Field Magnetometer (QTFM) is a compact, high-sensitivity scalar magnetometer. It can operate in Earth’s field, is extremely accurate and can resolve very minute field changes. Our sensor is among the highest performing in the world. A compact, low-power package makes it ideal for use in a wide range of existing and emerging applications such as in magnetic observatories and aboard small, mobile platforms.
