The DL2e logger is an easy to use field data logger, well suited to remote site and laboratory applications. The DL2e system offers a wide choice of sensors, logging intervals, data collection and analysis facilities.

The applications for this logger are endless and thousands of DL2e loggers are already installed. Standard software includes LS2e, for setting up and controlling the logger. The software also comes with a library of sensor descriptions, and software to allow the Psion Workabout (hand-held terminal) to collect data andload new configurations into the logger.
