01 / Instrument position

Density does not have to mean distance.

Octopus 16 moves sixteen inputs, conversion, embedded compute, and wireless transfer into one compact assembly. The signal remains inspectable even as the instrument leaves the desk.

02 / Signal route

From local contact to browser.

Four layers carry the acquisition from electrode inputs into a wireless application without hiding the hardware between them.
