Calibration & Repair Services for all makes of electrical & mechanical test equipment
The Sonel PQM-707 power quality analyzer is a portable center for power quality analysis. This mobile device enables measuring and analyzing power supply, and it is a versatile meter that operates independently. With the Sonel PQM-707, you can perform measurements and analyses of parameters in both DC and 50/60 Hz power networks.
The device has a memory for storing recorded parameters, and it performs class S measurements in accordance with the requirements of IEC 61000-4-30. As a result, it delivers highly accurate results.
Anti-theft feature – SMS notification in the event of position change (built-in GPS receiver).
