    Troubleshoot, quantify energy usage and perform quality of service surveys easier than ever

    It provides you with fast and easy access to the data you need to make real-time decisions, about critical power quality and energy.


    Compact and rugged, this three-phase power quality logger is specifically for technicians and engineers who need the flexibility to troubleshoot, quantify energy usage and analyze power distribution systems. Fully compliant with international power quality standards such as IEC 61000-4-30 and capable of simultaneously logging up to 500 parameters while also capturing events, this unit helps uncover intermittent and hard-to-find power quality issues more easily than ever. It comes equipped with an Energy Analyze plus software which quickly assesses the quality of power at the service entrance, substation, or at the load, according to national and international standards like EN 50160 and IEEE 519.


    An optimized user interface, flexible current probes, and an intelligent measurement verification function that allows you to digitally verify and correct connections make setup easier than ever and reduce measurement uncertainty. Minimize your time in potentially hazardous environments and reduce the hassle of suiting up in PPE by using a wireless connection (WiFi) to view data directly in the field.
