The instrument is designed based on Hall Effect Principle, it is a benchtop model, features wide measuring range, high resolution and stability, and sound accuracy. Its electronic circuitry is of 0.05% linearity, the accuracy for this meter mainly depends on the magnetic linearity and stability. Accuracy for SG-41 teslameter is 0.5%, while for SG-42/43 is 1%. Among them, SG-43 is of dual passage design, with each probe's adjustment and magnifying circuit functioning independently, so as to enable the output for shifting process be stable.
It is also equipped with analogue output window, which can connect with oscillograph, function logging device and other measuring meters to observe the changing waves for magnetic fields, thus it can measure the average, effective and peak value for the AC fields indirectly.
