Sonel Power Quality Analysers and Energy Loggers are Certified to make and record all EN61000-4-30 measurements of power quality parameters to Class A and Class S accuracy. The portable Class S range of PQM Power Quality Meters (PQM-700 and PQM-707) and Class A range (PQM-710, PQM-711 and PQM-750) are approved and appear on the ETL Energy Technology List.
The meters and software allow for measurements of important disturbances that can cause bad power quality including Harmonics, Voltage Dips, Interruptions and Swells.
All the portable meters carry a rating of IP51 to IP65. There is integrated GPS for full Class A compliance on the PQM-710 and PQM-711 along with GSM/M2M Sim capability to give remote access.
Monitoring in compliance to EN50160 is as standard with the meters compatible with networks with a nominal voltage of 64/100V, 110/190V, 115/200V, 127/220V, 220/380V, 230/400V, 240/415V, 254/440V, 290/500V, 400/690V along with DC networks.

The Sonel PQM-711 versatile power quality analyser for remote analysis in the A class is a device suitable for use on all types of networks with a rated voltage range from 110 V to 1000 V either directly or indirectly through transformers. Based on advanced technology, the Sonel PQM-711 power quality analyser allows comprehensive measurement, analysis and recording of 50/60 Hz power network parameters and power quality according to the European standard EN 50160.
-
The Sonel PQM-710 power quality analyser is a device with extended capabilities for remote analysis in class A. Sonel PQM-710 is a power quality analyser based on advanced technological solutions, with the use of which it is possible to perform comprehensive measurements, analysis and recording of 50/60 Hz power network parameters and power quality in accordance with the European standard EN 50160.
-
The Sonel PQM-700 meets the demanding standards of the IEC 61000-4-30 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.
-
The Sonel PQM-707 power quality analyser is a mobile device for measuring and analysing power supply. It is an autonomous and versatile meter with which you can carry out measurements and analyses of parameters in power networks (DC and 50/60 Hz). Tested parameters can then be recorded in the device's memory. The device performs class S measurements in accordance with the requirements of IEC 61000-4-30, ensuring highly precise results. The PQM-707 features also the largest touch screen in this class of analysers, with a resolution of 7 inches, which translates into high readability and ergonomic operation. The built-in lithium-ion battery guarantees efficient operation for a long time without having to connect the instrument to an external power supply.
