The Miro PQ45 is a Class A portable power quality analyser that can measure a comprehensive range of power quality parameters. With it’s IP66 rating, the Miro PQA can be installed outdoor in the most severe weather conditions.
The Miro PQ45 is a Class A portable power quality analyser that can measure a comprehensive range of power quality parameters. With it’s IP66 rating, the Miro PQA can be installed outdoor in the most severe weather conditions. The PQ45 has the highest safety rating of all portable power quality analysers – CAT IV 600V. The fourth voltage channel on the PQ45 allows for ground-neutral voltage measurements. The integrated remote communication module (optional) allows the user to access the Miro unit from anywhere in the world, letting them change configurations, download data files, and view all data in real time through the online monitor. The Miro comes with the easy-to-use Citrus software which is equipped with one-click compliance reporting features.
