The ImpedoDuo contains 2 x separate GPS synchronised instruments in one, each with 4 x voltage and 4 x current 16 bit ADC inputs. It is housed in a rugged machined aluminium enclosure and features an on-board GPS, a high-resolution LED Display which is also a multi-touch man-machine interface, 2 x Gigabit Ethernet ports and 2 x USB2.0 (HS) ports. Communication is secure and the instrument password protected.
