Envco Australia – Environmental Equipment

The DST tilt is supported by the SeaStar software and the Communication Box which serves as an interface between the logger and a PC. Communication between the logger and the Communication Box is wireless*.

In SeaStar, the user sets the start time, start date and sampling interval before starting the recorder. Up to seven different intervals can be set for the same measurement sequence. This is especially useful when more frequent measurements are needed at a certain time period.

With default programming depth, temperature, and tilt are recorded at the same time. Optionally, temperature-depth and tilt can be set as primary and secondary parameter pairs/parameters with different sampling frequency. That way memory partitioning can be customized according to individual preferences.

When the DST has been recovered, recorded data is uploaded to SeaStar where results are displayed both in graphic and tabular form. After retrieving the data, the DST can be re-programmed and reused as long as the battery lasts.

A set of Communication Box and SeaStar software needs to be purchased with the first order.

Features
Temperature calibration outside standard range
Temperature calibration outside standard ranges or for smaller ranges is available for all products on request.

Applications
DST Tilt can be used for analyzing movements and behavior of marine animals as well as for studying various underwater gear e.g. rotating fishing gear, nets etc.

The DST Tilt is suitable for studies in e.g. :
• Marine animal tagging (internally and externally)
• Oceanography
• Marine biology
• Ichtiology
• Hydrology
• Ecosystems research
Any other field where temperature, pressure and tilt monitoring is required
