With many years of magnetic field testing experience, G93 Handheld 3-Axis Gaussmeter, introduced by COLIY, is designed for scientific research institutions, universities, laboratories, industry, manufacturing andother users. G93 Gaussmeter 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 andvector of Magnetic Flux Density, and Trend Graph etc.).
There is a unique feature for 3-axis probe of G93: With the MEMS manufacturing technology, 3-axis probe provides very high spatial resolution (magnetic field sensitive volume 0.1 x 0.1 x 0.1mm3), orthogonality error is less than 0.1°, and the thickness of 3-axis probe is only 2mm.Gaussmeter G93 could fulfill many kinds of applications of institutes,universities and high technology enterprises.
Gaussmeter G93 could be equipped with different kinds of 3-Axis Probes: Standard Probe, Wide-range Probe and Temperature sensor-contained Probe. Its measurement range spans 107 from 1μT (0.01G) to 20T (200kG) with a basic accuracy of 1% or 0.5%.
Gaussmeter G93 with standard probe allows measurements up to 30kG (3T), and the frequency response of DC~ 1kHz; Gaussmeter G93 with wide-range probe, suitable for super conducting magnet, allows measurements up to 200kG (20T), and the frequency response of DC~ 1kHz; Temperature sensor-contained probes (probes with built-in temperature sensor) have the function of temperature compensation; temperature sensor-contained probes are strongly recommended for better precision and stability when the temperature changes.
Gaussmeter G93 has passed the CE certification and EMC (Electromagnetic Compatibility) test.

GUI Operation System
With the handheld instrument operating system (GUI Operation System) developed by COLIY, it’s very efficient and convenient for operators to choose menu by touching, to operate gaussmeter.
Color LCD shows magnificent data: time,value, polarity, Max, Min, note, Alarm, XYZ axisand vector of Magnetic Flux Density, trend graph.
The right is G93’s standard display mode.
Smart Record and Review
Detailed recordlist, operators can use MEMO to memorize any specification of every measurement.
Click any record list, operators can review all the information recorded as screen shots and add note to every item.
G93 has many display modes to be chosen: Standard Mode, XYZ Mode, Graph Mode, Polarity Mode and Simple Mode.
And XYZMode shows vector value, XYZ axis values and alarm threshold value.
TheThree-Axis sensor adopts particular MEMS technology with high spatial resolution, three mutually orthogonal magnetic field sensitive volume is 0.1 x0.1 x 0.1mm3 and orthogonality error is less than 0.1o.
There is not temperature sensor contained in the ordinary probes of Gaussmeter G93, and the typical temperature coefficient is ±500ppm/°C. However, temperature sensor-contained probes have the function of temperature compensation, so temperature sensor-contained probes are strongly recommended for the best precision and stability when the temperature changes.
G93 could show the clear polar indication by a colorful and dynamic cartoon picture. Picture in the left is adopted from Polar Mode displayed in the LCD screen during operation.
3-Direction Precision Movement Platform, is made of non-magnetic material. Users fixed the probe on the bracket front-end, and then manually rotate the knob so that the probe moves stably along the X, Y, Z-axis to a certain position and lock fixed.Maximum stroke of each axis is 150mm, and positioning accuracy is 0.1mm.
Provides up to 80 dB attenuation in fields up to 500 G, it could also be used to the zero calibration of standard probes.
Internal dimension of the Chamber: diameter 6.8mm x 44.5mm
SMART PC Software
SMART computer software has rich features: Automatically record and display trend graph; Display XYZ axis and vector of magnetic flux density, maximum and minimum in real time; Export saved data from the gaussmeter host; Record and save measurement data in real time.
Metal Protector of Probe
All COLIY gaussmeters’ probes have metal protectors (protective sleeves), and metal protector could be tightened with probe grip, to protect probes from impact, compression and other damage. It is strongly recommended when finished the magnetic field measurements, users should tighten the protector.
