Description

Resistant to any conditions, the Sonel PQM-700 power quality analyser is an effective device for analysing and recording network parameters. Based on advanced technology, the Sonel PQM-700 power quality analyser is effective for measuring, analysing and recording 50/60 Hz power network parameters. It is also used to control the quality of electricity in accordance with the European standard EN 50160 and the Regulation of the Minister of Economy of 4 May 2007 on detailed conditions for the operation of the power system. The extensive measurement capabilities of this device will be appreciated by a wide range of users who need a portable device to check the quality of electricity. The Sonel PQM-700 meets the demanding standards of the IEC 61000 standard for Class S analysers related to measurement uncertainties and measurement methods. This meter model is intended for those users who do not need a Class A analyser, as the PQM-700 provides comprehensive measurements of power quality parameters in Class S in accordance with IEC 61000-4-30.
