The Baseline 9000 Keeper software is used with an external computer connection to Series 9000 Hydrocarbon analyzers. The software provides total control of the instrument's set-up for alarms, relays, calibration, temperature, flows, configuration, data export, and real-time data viewing. Different set-ups can be stored as methods on a PC which can easily be loaded into the instrument for quick parameter changes on different applications. The computer can be connected directly to the analyzer with either a RS-232 or Ethernet connection. When the instrument is connected to a network it can be accessed using 9000 Keeper on a computer with a network connection.
