Bartington Instruments

Bartington Instruments is a world leader in the design and manufacture of fluxgate magnetometers, magnetic field sensors, magnetic gradiometers and magnetic susceptibility measuring instruments.

Magnetic Susceptibility System
The MS2 Magnetic Susceptibility System is used for mineralogical studies of rocks, soils and sediments in environmental research. These measurements are diagnostic of specific processes such as burning or soil waterlogging. Minerals can be identified using the MS2 Susceptibility/Temperature equipment, through determination of Curie points and low temperature transitions. A borehole magnetic susceptibility tool is available for operation to a depth of 6,000m.

Single-Axis Fluxgate Magnetometers
A range of single-axis fluxgate magnetometers is available with readout for DC and low frequency measurements and with analog outputs for measurements to a few kHz. Applications include site surveys prior to the installation of MRI and other magnetically sensitive equipment and use in active shielding measurements. A magnetometer with low radio frequency emission and a high tolerance to cross-fields is also available for MRI applications.

Triaxial Fluxgate Magnetometers
The Bartington range of three-axis magnetic field sensors has applications in physics, bioelectromagnetics, aerospace and defence. Low noise versions are available and sensors can be designed to customers' requirements.

Fluxgate D/I Magnetometer
The Mag-01H fluxgate declinometer/inclinometer is used by magnetic observatories and mapping agencies to measure the variation in the declination and inclination of the earth's magnetic field. The fluxgate magnetometer probe is mounted on a suitable non-magnetic theodolite.

Magnetic Gradiometers
Single and three-axis magnetic gradiometers are available with baselines of 12 inches, 500 mm and 1m for land and marine use.

Fluxgate Magnetometer Measurement Range
A fluxgate magnetometer is suitable for measurements from zero up to 2mT(20 Gauss) and can have a resolution of better than 1nT(10 microgauss) with a noise of a few pT.
