UNI-T UT803 Bench Multimeter
The UNI-T UT803 is a highly applied digital bench-type True RMS multimeter designed for scientific research, engineering, and professional electronics work. Featuring a unique outlook design with a large LCD display, this meter offers both autorange and manual range options with a maximum reading of 5999 counts and 3 5/6 digits resolution. It provides comprehensive measurement capabilities including DC and AC voltage and current, resistance, capacitance, frequency, temperature, diode, continuity, and transistor hFE testing.
Equipped with advanced data logging features, the UT803 includes RS-232C and USB standard serial ports for easy connection to a computer. This allows users to realize macro recording, monitor and capture transient dynamic data, and display waveform changes during measurement. The meter also features a display backlight, data hold, max/min recording, sleep mode, and full overload protection, making it an essential tool for engineering technicians and laboratory environments. It can be powered via an AC power cord or batteries for flexible bench use.
