The Mag-13 MCD from Bartington Instruments is a Magnetometer with circular enclosure with low noise. This magnetometer has a measurement range of ±250 µT 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 10pT rms / √Hz @1Hz. It has a maximum bandwidth of 1100 Hz at full scale and scaling of 40 mV/µT. It has It requires a supply voltage of 12-17 V and a current consumption of 35-41 mA. The magnetometer has a mass of 82.5 g and measures Ø 25.4 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.
