Bartington Instruments manufactures many single axis fluxgate sensors and magnetometers, which are used in many applications.
Mag-01H Portable, high resolution magnetometers with measuring range up to ±2mT, and maximum display resolution of 0.1nT. Range of fluxgate probes include longitudinal and transverse for ambient temperature and longitudinal for cryogenic applications.
Mag-01H D/I High accuracy Declinometer/Inclinometer unit with high-stability fluxgate probe mounted onto a non-magnetic optical theodolite. Display resolution down to 0.1nT. Commonly used in Intermagnet observatories for high precision measurement of the declination and inclination of the Earth's magnetic field.
Mag646 Low cost, unpackaged, single axis sensor with measuring ranges from ±100µT to ±1000µT. Two sensing element orientations are available. Typically used for detection of magnetic material.
Mag670 Low cost, packaged, single axis sensor with measuring ranges from ±100µT to ±1000µT. Two sensing element orientations are available. Typically used for detection of magnetic material.
Mag678/679 Low power sensors with measuring ranges of ±60µT or ±100µT, low noise option to ≤10pTrms/√Hz at 1Hz. Available with bandwidth of 1kHz (Mag679 only), a range of enclosure, including submersible are available. Typically suited to battery powered or surveillance applications
Mag592 A single axis sensor with low emitted radio-frequency radiations. Measuring ranges from ±70µT to ±1000µT and with bandwidth up to 2kHz. Typical applications include magnetic field measurement around permanent magnet MRI.
