UNI-T 3 Phase Power Quality Analyzer TRUE RMS Flexible Current Clamp 1000A THD

UT285C is a new product specially designed for power quality analysis.

It adopts latest microprocessor technology and digital signal processing technology, which can provide safer, more convenient, and more accurate measurement as well as troubleshoot power supply network.

With portable and humanization design, user can approach series of parameters of characterization of power quality, including voltage deviation, frequency deviation, harmonics and inter harmonics, unbalance, swell and sag, flicker as well as transient and surge signals.

These data can help users to locate and eliminate existing or potential problems and access the power quality.
