DC Ammeter
FZB Series Power Supply Intelligent Voltmeter Digital Display Voltmeter
FZB series digital indicating instruments (hereinafter referred to as digital instruments) are manufactured by our company based on many years of experience in producing DC system equipment. They are used to measure voltage and current in AC and DC systems, temperature, AC voltage and current. Except for the temperature digital instrument, the other digital instruments do not have the local display function of the measurement results. All digital instruments can communicate with the host computer through RS485 to achieve decentralized measurement.
