TM7600 is a series of high precision magnetic flux measuring instruments, using advanced digital sampling and integration methods. It overcomes the defects of traditional capacitance-integrated (RC-integrated) fluxmeters, such as the long-term drift of capacitance, piezoelectric effect, leakage current and bias voltage/current of amplifier, which lead to the difficulty of improving the measurement accuracy and the obvious integral drift after clearing. It provides an effective measurement method for the research and development of advanced magnetic materials, the manufacture of high-end industrial products and the traceability of magnetic flux value.
