Digital AC Voltage Test Equipment Dual Channel Millivoltmeter with USB Interface

Overview:

Model SP1931 is a general-purpose intelligent dual-channel digital AC millivoltmeter, which adopts the amplification - detector working principle and high-grade microcontroller control technology, suitable for measuring frequency 5Hz ~ 3MHz, voltage 100uVrms ~ 400Vrms sinusoidal RMS voltage. The instrument adopts green LED display, clear reading, good vision, long life. Meanwhile, it has the advantages of high measurement accuracy, fast measurement speed, high input impedance and small frequency response error. The whole machine has low power consumption, small volume, light weight, with automatic/manual measurement function, at the same time can display the voltage value and dB/dBm value, as well as the range and channel status, the display is clear and intuitive, easy to use, can be widely used in factories, laboratories, scientific research units, troops and schools, is the voltage measurement and testing of the necessary basic instruments.
