sketch:
G81Gaussian meter is a general-purpose high-performance handheld single dimensional Gaussian meter that usesCOLIYThe company's third-generation semiconductor gallium nitride(GaN)Hall sensor. Gallium nitride sensors have the characteristics of good temperature stability, not affected by light, high linearity, and low noise, and their performance is ahead of the second-generation semiconductor gallium arsenide(GaAs)Sensor technology.
Gauss meters require frequent zero calibration during start-up and measurement, which is cumbersome to operate and affects accuracy.G81Gaussian meter is usedBypass Zero TechnologyPatent technology and high stabilityGaNHall sensors do not require zero calibration, greatly improving the accuracy and ease of use of data.G81It also has unparalleled extremely low measurement noise compared to handheld Gaussian meters, with a resolution of up to0.01GIt is easy to measure the remanence of metal materials and even the Earth's magnetic field (approximately)0.4G).
Gauss meterG81ofDCAccuracy better than0.8%, with a range of up to100kG (10T)Frequency response rangeDC-10kHzGaussian meterG81Measurement of AC magnetic field using Fourier analysis method(RMSValue and Spectrum Analysis)It is very suitable for measuring various waveforms in communication(Sine wave, square wave, triangular wave, trapezoidal wave, sawtooth wave, etc)The magnetic field. Gauss meterG81use3.2The inch color industrial resistance touch screen and menu and display that conform to the habits of smartphones are easy to operate, and users can use them without reading the manual; Gauss meterG81Powerful functionality with maximum value/Minimum value function, magnetic field polarity display function, storage function, real-time spectrum analysis function, and0.2msPulse magnetic field capture function. Gauss meterG81pass throughCEauthentication.
Users can choose from multiple probes: radial probe, axial probe, high-temperature probe, low-temperature probe, miniature axial probe, ultra-thin probe(0.5mm)And probes with temperature compensation. Conventional probe temperature coefficient±300ppm/℃The temperature coefficient of the probe with temperature compensation is only±50ppm/℃It can greatly improve measurement accuracy and stability during temperature changes, so it is strongly recommended to purchase probes with temperature compensation.

Note:
1. The most cost-effective package (high-precision, low-temperature float): G81+PROBE T08M150G81T;
2. The model ends with the letter "T": a probe with a built-in temperature sensor and temperature compensation function, with a typical temperature coefficient of<± 50ppm>± 50ppm>
3. Each probe is calibrated to 2.5T; the accuracy of 2.5T-10T is determined by the linearity of the Hall sensor, and it is hoped that the accuracy parameters can be achieved, but cannot be guaranteed.According to the test report from the China Institute of Metrology, the DC accuracy of the Gaussian meter G81 is better than 1% within the range of 2-7T.[See link for details]
