The Mag-13 MS from Bartington Instruments is a Magnetometer with square enclosure with standard noise. This magnetometer has a measurement range of ± 70 µT to ± 1000μT and a frequency response of ± 5% amplitude error DC to 100 Hz. The magnetometer has an offset error of less than ± 30 nT and a noise level of less than 10 pT rms/√Hz @1Hz. It requires a supply voltage of 12-17 V and a current consumption of 35-41 mA. The magnetometer has a mass of 222.6 g and measures 32 x 32 x 203mm. It is ideal for a magnetic field monitoring, feedback sensors in active magnetic field cancellation systems, magnetic signature measurements and electromagnetic surveys applications.
