The Atto is a microprocessor based transducer energy analyser which has flexibility and accuracy designed to meet the most demanding applications of electrical parameters analysis and energy supply monitoring in the residential, tertiary and industrial sectors.

DC versions are available for direct current readings in solar PV photovoltaic and telecommunications systems.

The Atto E-Wi has the same features of the Atto without inputs and outputs and in addition can transmit and receive the data via radio waves, without limitations (wireless) using the E-Wi protocol based on the IEEE 802.15.4 standard.
