The Sonel PQM-707 is a powerful, portable power quality analyzer for comprehensive measurement, monitoring and analysis of power supply networks (AC & DC). It meets all requirements of class S according to IEC 61000-4-30 and thus offers the highest accuracy for professional applications – whether in industrial plants, supply networks or at service providers.
Thanks to autonomous power supply (Li-ion battery), a large 7“ touchscreen, replaceable memory card and intuitive operation, the PQM-707 is ideal for mobile use directly at the measuring location – even under harsh conditions.
