The Eurotherm Nanodac graphic recorder offers four channels of precision analogue batch recording, meeting the requirements of regulators for accuracy and repeatability as well as data logging requirements of 21 CFR 11. The recording functionality utilizes secure strategies and UHH format developed in-house by Eurotherm. Multiple data archiving methods are achieved through the built-in 50MB onboard flash memory, removable USB devices, and data transfer via FTP to a specified server. Multiple real-time views and historical review is also built-in to the Nanodac. The four universal input channels provide high accuracy and 125ms parallel sampling. An additional 30 virtual channels can be enabled to provide maths, counter, slave communications, and totalizer functionality within the instrument.
