The Miro PQ35 Three Phase Power Quality Logger and Analyser is a Class A, CAT III 600V, three voltage channel (3P + N), high precision, weatherproof (IP66) instrument that offers comprehensive power quality measurements, including Voltage Sags, Swells, Interruptions, Flicker, THD, Harmonics, Interharmonics, Temperature, Frequency, Mains Signalling, Power and Energy.

Waveform and RMS captures can be generated, using various triggers, e.g. rate of change of voltage (dv/dt), sliding reference, and instantaneous voltage and current values. Alarm lists can be generated when set thresholds are exceeded. The Miro PQ35 is WIFI enabled, comes with various communications protocols and optional integrated remote cellular communications. The Miro PQ35 is the instrument of choice for comprehensive power quality ideal instrument for compliance reporting, energy audits, investigating customer complaints and fault finding.
