The UNI-T UTE9800 Series intelligent electrical parameter tester (digital power meter) adopts high-speed ADC and 32-bit MCU computing architecture, supporting True RMS AC/DC/AC+DC composite measurement, suitable for full-wave, half-wave and irregular distorted waveform testing.

It simultaneously measures voltage, current, active power, apparent power, power factor, frequency, voltage/current crest factor; the UTE9811/UTE9811+ model supports PLL synchronous harmonic analysis up to 50 orders.

Equipped with 5-digit VA color segment LCD multi-window synchronous display, auto-range switching for voltage and current, built-in upper/lower limit visual & audible alarm with delay setting. Standard RS-232 & RS-485 dual communication ports, compatible with SCPI and Modbus protocols, easy to connect with PLC/PC to build automated test systems.

Compact half 2U rack-mount chassis, stable measurement, simple operation, widely used in household appliances, lighting, power tools, motors, switching power supplies, laboratory R&D and factory quality inspection lines.
