Underwater Temperature Recorder

Starmon mini is an underwater temperature recorder designed for use in oceans, rivers, and lakes. Starmon mini records the temperature and stores the data in memory. The recorder is operated with our SeaStar software and a PC communication cable, which are the necessary accessories to operate and communicate with the recorder. When Starmon mini is connected to a computer, the software can be used to set up the sampling interval and start time of the recordings. After the recorder has been recovered from the deployment site, the data can be retrieved by connecting the Starmon mini to a computer and use the software to upload data from the recorder.

The data can be processed and presented in graphs and in tabular form. All measurements are time related. Data can be exported into other data processing software. Starmon mini has an all plastic housing that is robust and does not corrode in the sea. For more extreme pressure the Starmon mini is available in non-corrosive titanium housing.

Applications

Applied researches are within the fields of oceanography, limnology, aquaculture, ecology, marine biology and fishery research. Starmon mini can also be used for terrestrial use or as an air temperature recorder.

Easy to use

Simply unscrew the end cap and connect the communication cable between the recorder and a computer. The cable has a 9 pin RS232C serial connector, but an optional USB serial converter is available. SeaStar software for Windows is used for communicating with the recorder.
The Starmon mini is a low power consumption recorder, it is powered by a single lithium battery (1/2 AA size) that lasts for 7 years or more, depending on sampling interval and usage. In case battery fails, data is always kept in the non-volatile EEPROM memory. Battery can be replaced using a soldering iron.
