Digital Tesla Meter Gauss Meter Field Strength Meter for Magnetic Particle Inspection HGS-10C
The Tesla meter is a special instrument used for inspecting & checking flux density ,which is also one of the most universally devices in the field
of magnetic measurement.
Model HGS-10C digital Tesla meter is controlled by the SCM, which is suitable for handle operation.It can be used to measure DC or AC magnetic field and flux dencity.The device can be carried on one’s person. It is characterized by its wide measuring range,simple operation and clear display. It is still added with the function of maintenance such as holding Measure Value/Peak Value, As mT or Gs unit of display can be change over, Measuring range of 200mT or 2000mT can be chose, and others that as resetting zero by key and so on. The power is one piece of battery 9V. It can be used continually about 20 hours.
Reality Working Domain:
Principle of Hall Effect
When placing the semiconductor carrying current in the magnetic field axial to the current direction, the semiconductor will generate transverse galvanomagnetic phenomenon, namely generate electromotive force in the direction axial to the magnetic field and current, which is Hall Effect. Hall Effect can be explained with classical galvanomagnetic theory. Generally, Hall voltage UH is expressed as:
UH=RHIB0/d= RHIIB0
Of which: d—the thickness of the Hall device
RH—Hall constant
RHI=RH/d—Constant of the Hall device
I—Current intensity passing through the Hall device
B0—The measured magnetic induction intensity
It can be seen from the formula: For a certain Hall device, the magnetic field B0 can be indirectly measured through measuring the Hall device if only the passing current I is constant. Since it can count continuously and linearly with simple method and long service life when measuring the magnetic field with Hall Effect and can measure the magnetic field of small space and small gap, Hall Effect Method has become one important method among magnetic field measurements
HGS-10C is the first hand-held type Gauss meter of HGS series Gauss meters. This instrument is the magnetic field measuring instrument specially designed for field measurement. Its design concept of lightness, practicality and portability has been determined at the beginning of instrument design and its unique design of micro power consumption allows its battery life to be greatly improved.

III Instrument operating instruction
Step 1: Connection: connect the Hall probe with the instrument⑥;
Step 2: Power on: Press the “POWER” switch ②on the panel of handhold Gauss meter and there shall be display ①on the panel meter, it represents the instrument power has been energized and measurement can be done;
Step 3: After the power is energized, firstly select a corresponding range ③according to the magnetic field size of the measured object.
Step 4: Zero point correction: Place the Hall probe in the area whose magnetic field is zero. When the meter reading is not zero, adjust “Zero” ⑤potentiometer till the reading is zero.
Step 5: Magnetic field measurement
A. Place the Hall probe in the surface magnetic field of the measured sample, move the Hall probe and the magnetic field intensity can be directly read from the instrument, whose unit is mT and the magnetic field polarity also can be judged (When using transverse probe and the display value is “-”, the number side of the Hall probe faces N pole and when using axial probe and display value is “-”, the end side of the Hall probe faces N pole);
B. The range button, the range is 2000mT when it is pressed and the range is 200.0mT when it bounces back;
C. Contact the magnetic steel surface with Hall chip side in the practical measurement, the measurement result is closer to the actual value. When measuring with base plate side, the measurement result is little low, 1mT = 10 Gs.
IV Instrument calibration
Place the Hall probe in the standard magnetic field and adjust the “Calibration” ⑦potentiometer with small slotted screwdriver till the instrument reading is consistent with the numerical value of the standard magnetic field. Generally, it will be required to calibrate the instrument only after the Hall probe is replaced.
