GF601 Single-AxisFluxgate Magnetometer
Description:
The 2025-Version Three-axis Fluxgate Magnetometer GF601, madeby COLIY, has the excellent ergonomic design with the latest electronic technology, and it’s one of best choices to measure low-intensity magnetic field. This handheld fluxgate magnetometer can be used in geomagnetism detection, wrapped detection, traffic monitoring, measuring residual magnetism, low-intensity magnetic field measurement, etc.
The key feature of the 2025-Version Magnetometer GF601 is that the size of the probe is reduced to only 24x24x50mm, which is only 1/4 ofthe size of the old version, and it is one of the smallest high-performance fluxgate probes at present, which can be measured in a small space. Magnetometer GF601 adopts a high-precision 24-bit ADC chip, which greatly improves the magnetic field resolution. High performance circuit supports the measurement resolution of 0.1nT within the full measurement range. The power consumption of the whole machine is reduced by 1/4. Magnetometer GF601 boasts with an industrial class 3.2 inches touch panel display that enables customers’ instantaneous and simultaneous measurement results [Max/ Min/ Peak/ Hold/ Alarm/ Polarity, Magnetic Flux Density,and Trend Graph etc.].
Magnetometer GF601 can be used to detect DC magnetic field in DC measurement mode and AC magnetic field in AC measurement mode respectively: GF601 allows DC measurements with a basic accuracy of 0.5%, resolution of 0.1nT and AC measurement with a basic accuracy of 1% and frequency response range of DC~ 2kHz.
In addition, Magnetometer GF601 has passed the CE certification and EMC(Electromagnetic Compatibility) test.

Note:
1, AC Range mentioned above refers to AC magnetic field measurement range after DC magnetic field is shielded, so if DC magnetic field is not shielded, and users want to measure magnetic field in AC measurement mode, AC Range is equivalent to the value that 0.7 times of DC Range minus DC magnetic field intensity. [SQRT(2)/2 ≈ 0.7]
