ONET networking software is for the setup, administration and control of large FT-NIR spectrometer networks. It is a server application accessed via a browser-based Web interface (WebUI), allowing users to set up, administrate and control a network of FT-NIR instruments from a central remote location anywhere in the world. All data measured on local spectrometers are stored first locally and replicated to a database for central access. The software supports the connection of LIMS to the central data base and is available in English, Chinese, French, German and Spanish. The number of clients in the network is only limited by the performance of the server and the network data transfer rate.
