Gaussmeter G401 is a desktop precision single-axis gaussmeter using COLIY's third-generation semiconductor gallium nitride (GaN) Hall sensor. Gallium nitride sensor has the characteristics of good temperature stability, unaffected by light, high linearity, and low noise, and its performance is ahead of the second-generation semiconductor gallium arsenide (GaAs) sensor technology.
The gaussmeter needs to be calibrated frequently during startup and measurement, which is inconvenient to operate and affects accuracy. Gaussmeter G401 adopts Bypass Zero Technology and high-stability GaN hall sensor, no need to zero, which greatly improves the accuracy of the data and the convenience of use. Gaussmeter G401 is usually equipped with a hall probe, and a low-field probe is optional. The hall probe and the low-field probe have separate sockets, which can work and display at the same time, which makes the G401 Gaussmeter have an extremely wide measurement range from 10nT to 10T.
With the GaN hall probe, the DC accuracy of Gaussmeter G401 is better than 0.04%, the measurement range is up to 100kG (10T), and the frequency response range is DC-10kHz. Gaussmeter G401 has up to 7 display digits, and has extremely low measurement noise in the full scale range, with a typical DC magnetic field noise of 0.01G (1μT).
With the low-field probe, the DC accuracy of Gaussmeter G401 is better than 0.2%, the measurement range is up to 6G (600μT), and the resolution is up to 0.1mG(10nT). Due to the compact size, the low-field probe is very suitable for measuring weak magnetic fields, especially in narrow space.
Gaussmeter G401 adopts a 10.1-inch color industrial resistive touch screen and a built-in GUI operation system, which is easy to operate, and users can use it without reading the manual; G401 adopts aviation aluminum alloy shell, which is small in size and saves desktop space; G401 adopts a low-power fanless design, which is green and environmentally friendly.
Gaussmeter G401 is powerful, with maximum/minimum function, magnetic field polarity display function, storage function, time domain graphfunction, oscilloscope function, real-time spectrum analysis function and 0.2ms pulse magnetic field capture function; G401 Gaussmeter has a variety of measurement modes: DC standard mode, DC time domain figure mode, AC standard mode, AC spectrum analysis mode, AC oscilloscope mode and 0.2ms pulsed magnetic field measurement mode to meet various complex magnetic field measurement occasions. In addition, Gaussmeter G401 uses Fourier analysis method to measure AC magnetic field (RMS value and spectrum analysis), which is very suitable for measuring AC magnetic field of various waveforms (sine wave, square wave, triangle wave, trapezoidal wave, sawtooth wave, etc.).
Gaussmeter G401 could be equipped with many different kinds of Hall Probes: Transverse Probe, Axial Probe and Probe with temperature compensation. The typical temperature coefficient of ordinary probes (probes without temperature compensation) is ±100ppm/℃, but typical temperature coefficient of probes with temperature compensation is only ±20ppm/℃, so probes with temperature compensation are strongly recommended for better precision and stability when the temperature changes.
Gaussmeter G401 has passed the CE certification and EMC (Electromagnetic Compatibility) test.
