Three-Phase Data Logger

Energy Monitoring

The Emonio P3 three-phase power measuring device determines the power consumption of house connection points, man and sub distribution points, devices and systems. It is especially suitable for mobile and temporary measuring of 1-phase and 3-phase AC power. Emonio P3 quickly and precisely delivers measuring results an can be quickly connected to any distribution cabinet.

Benefits of the Emonio Energy Monitoring System

Mobile, temporary energy measurement

Emonio P3 can be connected to any distribution cabinet. It is small, light and has a magnetic backplate.

Noninvasive power measurement

It uses rogowski coils or foldable current transformers are used to measure the voltage while magnetic tips are used for the voltage supply.


Emonio P3 is ready for diverse use and measures all single and three phase consumers. The power sensors are interchangeable with any other Emonio P3 unit.

Easy to configure

Emonio P3 is an ideal tool to simultaneously measure several consumers at different locations. It also features WiFi and MQTT interfaces.

No Software Installation Required

Measurement data is visualized in realtime in your browser or on your smartphone. Or laptop. You can download the measuring data and analyze it on

Certified Savety

Precisely record load curves by second, minute or hourly intervals with max. 1% deviation (precision class 1). Emonio P3 is pre-calibrated for immediate use.

Quality that convinces our customers

Measurement technology and analysis software are state-funded

The state promotes the use of measuring technology and software in companies if an increase in energy efficiency can be measured with it. The prerequisite is the establishment or application of an energy or environmental management system. If you intend to introduce one of these systems or need measurement technology, please contact us. We would be happy to advise you.

Information on the minimum requirements can be obtained from BAFA.
