The LI-840A is configured with a Windows® software application, which is provided with the instrument. The configuration software is used for configuration, control, data collection, and graphical data display. Your choice of parameters (CO2, H2O, cell pressure, or cell temperature) can be output via linear voltage or current outputs. In addition, 0-5V alarm outputs can be connected to audible alarms, relay switches, automatic dialers, pumps, or valves in industrial applications. The LI-840A is connected to a computer with the RS-232 DB9 serial cable connection.
