HOBO TidbiT v2 Water Temperature Data Logger
Only 3x4 cm, this tiny data logger measures temperatures over a wide temperature range. The TidbiT v2 provides 12-bit resolution and has ±0.2 °C accuracy.
Learn more about the compact temperature logger TidbiT v2 in the introductory video. You will receive information about the special epoxy coating, the water depth, the temperature accuracy in degrees Celsius and the statistics storage. The video also explains details about the battery, optical communication, enabling fast data transfer in water and about compatibility with the HOBOware Pro software.
The HOBO TidbiT v2 was specifically developed for outdoor and underwater applications to obtain precise data on temperature and water temperature.
Please note: An interface is required for configuration and reporting
- Our smallest HOBO temperature data logger
- Waterproof to 300 meters (1000 feet)
- Data download in less than 30 seconds via the Optic USB interface
Der Datenlogger HOBO TidbiT v2 unterstützt die kostenfreie Grafik- und Analysesoftware HOBOware. HOBOware ermöglicht Ihnen die einfache Anzeige und Analyse Ihrer aufgezeichneten Messdaten per Mausklick. Sie können den Datenlogger einfach per Kabel an Ihren Computer anschließen.
