Calibration & Repair Services for all makes of electrical & mechanical test equipment
The Sonel PQM-711 is a highly versatile power quality analyzer capable of remote analysis in the A class. It is designed to work on all types of networks with a rated voltage range of 110 V to 1000 V, whether connected directly or indirectly through transformers.
With advanced technology, the Sonel PQM-711 offers comprehensive measurement, analysis, and recording of 50/60 Hz power network parameters and power quality. It is capable of meeting the European standard EN 50160 and the Regulation of the Minister of Economy on detailed conditions for power system operation.
Anti-theft feature – SMS notification in the event of position change (built-in GPS receiver).
