Gauss Part 2: How to measure Gauss values for a PEMF device

The only reliable Gauss measurement method requires a visualization of the PEMF pulse, while simultaneously quantifying the Gauss value. For this purpose our company uses of the following measurement method, based on purely scientific methods.

A Hall effect sensor is a transducer where the output voltage changes depending on changes of a magnetic field.

A Hall probe has a magnetic field sensor that passes electrical current when the sensor is perpendicular to a magnetic field.


The stronger the field the more current passes through the sensor.

Curatronic makes use of a measurement procedure based on this Hall effect where the PEMF pulse is measured and visualized on an instrument called an oscilloscope, all at the same time.

For this Curatronic designed a sophisticated measurement device using a laser calibrated linear Hall sensor with temperature and offset compensation.

The output voltage of the Gauss measurement device is proportional to the magnetic flux density through the Hall sensor plate.


The temperature and offset compensations result into stable magnetic characteristics for the power supply voltage. This includes stabilizing changes that may occur in temperature, like temperature increase because of the pulse currents in the coils.

The Hall sensor measures constant and low frequency magnetic flux densities accurately. The device voltage output is proportional to the magnetic flux density passing vertically through the sensitive area of the Hall sensor.

The actual magnetic field strength measurement procedure is performed by placing the Hall sensor on the PEMF coil while at the same time showing the maximum pulse signal on the screen of the oscilloscope.


Because the field strength measurement is derived through a special electronic (differential and choppered) voltage amplifier for stability, the measured output signal consists of a positive and negative part, while the PEMF pulse itself is positive only.

Single PEMF pulse measurement

The picture at the right side shows an example of  a PEMF frequency of 1 Hz, with a 50% duty cycle and the measured real Gauss magnetic field intensity is 496 Gauss = 49.6 milli-Tesla.
