UNI-T UT285C Three Phase Power Quality Analyzer

UNI-T UT285C Three Phase Power Quality Analyzer in Sri Lanka

Handheld Harmonics, Flicker and Power Logging Instrument

The UNI-T UT285C is a handheld three phase analyzer that displays four voltage and current waveforms in real time. It measures true RMS values, peaks, harmonics, THD, flicker, K-factor, and phase unbalance. It suits electricians and energy auditors in Sri Lanka who need to trace supply faults and check installation quality.

It records active, reactive, and apparent power per phase and in total. It also captures transient events and stores trend data on built-in memory, with USB and PC software for analysis and reporting.
