A modern multipurpose measuring device to be built into a panel. With its design, it is intended for installation into all types of switchboards and other devices. It offers many functions and the option to save the data measured.

The instrument features excellent design and graphic, and introduces a fully new innovative dimension into the assortment of the company as well as into the measuring technology branch itself.

The instrument has a quite high inner resistance and low consumption thanks to the modern solution using high-quality electronic parts. The control is easy and intuitive through a touch display.

The display shows minimum and maximum values measured as well as the current value. Using the graph function, one can go through the history of measurement easily. The user can adapt the display appearance through selection of more graphic interfaces.
