GF603 Three-AxisFluxgate Magnetometer

 

Description:

The 2025-Version Three-axis Fluxgate Magnetometer GF603, 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 GF603 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 GF603 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 GF603 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, XYZ axis and vector of Magnetic Flux Density, Declination/Inclination(D/I), Trend Graph and Real-time Spectrum Analysis (with model GF603S) etc.].

Magnetometer GF603 can be used to detect DC magnetic field in DC measurement mode and AC magnetic field in AC measurement mode respectively: GF603 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. Meanwhile, Magnetometer GF603S has the function of real-time spectrum analysis within the frequency range 15Hz- 2kHz.

In addition, Magnetometer GF603 has passed the CE certification and EMC (Electromagnetic Compatibility) test.

Certification

CE Certification, EMC Certification

Note:

1, D- Declination, is the angle thatbetween the Z axis and the projection of the field vector onto the XZ plane.

2, I- Inclination, is the angle thatbetween the field vector and the XZ plane.

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