Description
Coliy Model G401 is a high-precision desktop single-axis Gaussmeter, which uses third-generation semiconductor galliumnitride (GaN) Hall sensor. Galliumnitride sensor has the characteristics of good temperature stability, not affected by light, high linearity and low noise, and its performance is ahead of the second generation semiconductor gallium arsenide (GaAs) sensor technology.
Ordinary Gaussmeter boot and measurement often need to zero, cumbersome operation, affect the accuracy. G401 Gaussmeter adopts Bypass Zero Technology and high stability GaN Hall sensor, which isready to start without Zero correction, greatly improving the accuracy and convenience of use.
The DC accuracy of G401 Gaussmeter is better than 0.04%,measuring range up to 100kG(10T), frequency response range DC-10kHz. G401 Gaussmeter has up to 7 display digits, very low measurement noise in the full range, typical DC magnetic field noise of 0.01G(1μT).
Gaussmeter G401 adopts 9 inches color industrial resistance touch screen, built-in graphical interface operating system, easy to operate by users; small size, save desktop space, low power consumption, low-power design,environmental protection.
Gaussmeter G401 provides advanced functionality, with maximum/minimum value, magnetic field polarity display, storage, time domain diagram, oscilloscope, real-time spectrum analysis and 0.2ms pulse magneticfield capture functions; G401 Gaussmeter has a variety of measurement modes: DCstandard mode, DC time domain diagram mode, AC standard mode, AC spectrum analysis mode, AC oscilloscope mode and 0.2ms pulse magnetic field mode, which can meet various complex magnetic field measurement occasions. G401 Gaussmeter adopts Fourier analysis method to measure the RMS value of AC magnetic field.The frequency response range is 0.5HZ-10kHz, which is suitable for measuring the magnetic field of sine wave, square wave, triangle wave, trapezoidal wave,sawtooth wave and other waveforms.
Gaussmeter G401 could be equipped with different kinds of Hall Probes: Standard Transverse Probe, Standard Axial Probe, and Temperature sensor-contained Probe. The temperature coefficient of ordinary probes is 100ppm/℃, but temperature sensor-contained probes(probes with built-in temperature sensor), whose temperature coefficient is down to 20ppm/℃, have the function of temperature compensation, so temperature sensor-contained probes are strongly recommended for better precision and stability when the temperature changes.
Gaussmeter G401 has passed the CE certification and EMC (Electromagnetic Compatibility) test.

GaN Hall sensor
GaN materials have the characteristics of strong atomic bonds, high thermal conductivity, good chemical stability and strong radiation resistance, and are known as the third generation semiconductor materials after the first generation of Ge, Si semiconductor materials, the second generation of GaAs, InP semiconductor materials.
The third-generation semiconductor GaN Hall sensor of COLIY Company is characterized by good temperature stability, high linearity and low noise, and its performance is ahead of the second generation semiconductor GaAs sensor. |
|
|
|
Bypass Zero Technology During the use of ordinary Gaussmeters, the magnetic field zero point of the host and probe will shift due to temperature changes and hysteresis, so the probe must always be put into the zero calibration chamber for zero calibration.
G401 Gaussmeter adopts unique BypassZero Technology proprietary technology and high stability GaN Hall sensor. Both the host and probe have excellent zero stability and low noise. Temperature and hysteresis do not affect the zero point of the Gaussmeter. Zero calibration isnot required during use, which greatly improves the accuracy of data and convenience of use. |
|

0.2ms pulse magnetic field capture function
G401 Gaussmetercan sample at high speed and capture positive and negative pulse magneticfields with time width ≥ 0.2ms, and the maximum pulse magnetic field value isup to 10T. The peak topeak value or peak value of the pulsed magnetic field can be selected accordingto the use scenario. This isideal for measuring magnetizers and other fast pulsed magnetic fieldapplications. |
|
|
|
Time domain diagram function G401 Gaussmeter can display the trend chart of magnetic field changes with time within 75 seconds and the current magnetic field value.
|
|
Real time spectrum analysis For AC magnetic field, G401 Gaussmeter has real-time spectrum analysis function,and the spectrum analysis range is less than 10kHz. Fourier is used to analyzethe AC magnetic field of 20Hz-10kHz, and the screen displays two maximum magneticfield peaks and frequency values.
|
|
|
|
Oscilloscope function TheG401 Gaussmeter is a breakthrough in integrating the magnetic fieldoscilloscope function, which can display the magnetic field waveform up to 5kHzin real time, or high-frequency noise disturbance.
|
|
Temperature compensation The conventional probe does not contain a temperature sensor, and its temperature coefficient is 100ppm/℃, while the probe with built-in temperaturesensor has a temperature compensation function, and its temperature coefficientis as low as 20ppm/℃, which can improve the accuracy and stability of measurement data when the temperature changes. Therefore, it is strongly recommended to purchase a probe with built-in temperature sensor. |
|
|
|
3D movable platform The three-dimensional mobile platform is made of non-magnetic materials. The userfixes the probe at the front end of the bracket, manually rotates the knob tomake the probe move steadily to a certain position along the X, Y, Z axisdirection, and locks and fixes it. The maximum stroke of each shaft is 150 mm,and the positioning accuracy is 0.1 mm.
|
|
Metal protective sleeve Allthe probes of COLIY Gaussmeter are protected by non-magnetic metal casing.
Thenon-magnetic metal sleeve can be tightened and fixed with the probe handle toprotect the probe from strong impact, extrusion, etc. It can prevent the probe from falling down at a height of 10 meters, and even resist the impact of ahammer. It is suggested that the user should tighten and fix the non-magnetic metal sleeve after completing the magnetic field measurement to protect the probe from damage to the maximum extent.

|
|
|
Splitde sign The host and base of G401 Gaussmeter are designed separately. With the base, theG401 Gaussmeter host can be placed upright on the desktop; Remove the base, and the G401 Gaussmeter host is used as a handheld tablet, which is flexible andconvenient. The mobile phone charging bank can be used as the mobile power supplyof the Gaussmeter.
