The Three-Axis Fluxgate TFM1186 is part of Metrolab’s THM1176 family, portable 3-axis magnetometers. It’s a lightweight, low-power consumption magnetometer that can be used anywhere. Its exceptional noise characteristics make fluxgate magnetometers the instrument of choice for measuring minimal disturbances in the local magnetic field, such as those caused by iron masses or noise from a power line. The TFM1186 has a range of ±100 µT (±200 µT on request) and a resolution of 4 nT.
