LZ-820 flux meter is a precision compositive flux meter, which uses different induction coil to measure alterable magnetic flux. The basic part is the analog integrator controlled by embedded microprocessor. Analog integrator is quite flexible, it can run good in different field. Embedded microprocessor not only improves the function of the integrator, and also adds a variety of useful functions to the machine.
LZ-820 flux meter reflects fast, easy to use, automatic operation mode and manual mode can be selected at random.
