Description:
G80 Gaussmeter (Magnetic Field Meter) is an Excellent Cost-efficient handheld single-axis gaussmeter using COLIY's third-generation semiconductor galliumnitride (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 galliumarsenide (GaAs) sensor technology. Adopted COLIY's Bypass Zero Technology and high-stability GaN hall sensor, Gaussmeter G80 has low zero drift, no need to zero adjustment, which improves the accuracy of data and the convenience of use.
The G80 Handheld Gaussmeter can be used to measure the surface magnetic field of permanent magnet materials, DC motors, speakers,magnetic separators, permanent magnet separators, and workpiece remanence measurement. It is widely used in magnetic material manufacturers and permanent magnet motor production. Manufacturers, permanent magnet iron separator manufacturers and application units, power industry and railway industry.
The Gaussmeter G80 uses a 3.2-inch black-and-white industrial resistive touch screen. It is easy to operate, and users can use itwithout reading the manual. Gaussmeter G80 allows measurements up to 2T (20kG) with a basic accuracy of ±2%, the resolution of 0.01mT (0.1G), and the frequency response of DC~100Hz. Gaussmeter G80 could be equipped with Axial Probe and Transverse Probe. Noise only 0.1G peak-peak within 60 seconds.
Besides, Gaussmeter G80 is powerful, with DC/AC measurement mode, magnetic field polarity (N/S) display function and maximum/ minimum measurement function. Gaussmeter G80 uses Fourier analysis method to measure AC magnetic field (RMS value), which is very suitable for measuring AC magnetic field of various waveforms (sine wave, square wave, triangle wave, trapezoidal wave, sawtooth wave, etc.).

 | Bypass Zero Technology
During the use of an ordinary gaussmeter, the host and probe will has zero drift due to changes in temperature and hysteresis. Therefore, the probe must be frequently placed in the zero-gauss chamber for zero calibration. The Gaussmeter G80 adopts unique Bypass Zero Technology and high stability GaN Hall sensor. Both the host and probe have low zero drift error and extremely low noise. Temperature and hysteresis do not affect the zero drift of the gaussmeter. There is no need for zero calibration, which greatly improves the accuracy and convenience of use. |
GaN Hall Sensor
GaN materials have the characteristics of strong atomic bonds, high thermal conductivity, good chemical stability and strong radiation resistance. GaN is known as the third-generation semiconductor materials, after the first generation of Ge, Si semiconductor materials and the second generation of GaAs, InP semiconductor materials. COLIY's third-generation semiconductor gallium nitride (GaN) Hall sensor has the characteristics of good temperature stability, high linearity and low noise, and its performance is ahead of the second-generation semiconductor gallium arsenide (GaAs) sensor technology.

Black and white LCD screen shows magnificent data: DC/ AC RMS measurement mode, real-time magnetic flux density, N/S magnetic polarity, Maximum and Minimum. |
Metal Protector of Probe All probes of COLIY gaussmeter are protected by non-magnetic metal protectors (protective sleeves). The non-magnetic metal protector can be tightened with the probe grip to protect the probe from strong impacts, squeezing, etc. It can prevent the probe from falling damage from a height of 10 meters, and even resist hammer strikes. It is recommended that users tighten and fix the non-magnetic metal sleeve after completing the magnetic field measurement to protect the probe from damage to the greatest extent. |
