Onset's housing makes it easier to mount its water level and conductivity dataloggers in streams, lakes and other bodies of water.

A white paper from Onset Computer Corp., Bourne, Mass., offers guidance and tips on selecting and deploying water temperature loggers. The dataloggers can be used for underwater monitoring in applications such as assessing industrial thermal loading from water discharge, but successful monitoring relies on handling challenges specific to particular field sites.

"Underwater Temperature Loggers: Considerations for Selection & Deployment" looks at the three main phases of operation — configuration and launch, deployment, and data retrieval and analysis. It can be downloaded from the white papers section of Onset's site, under the "Learning" tab on its main site navigation.
