Log your data without logging the miles. The beadedstream D605 Thermistor Data Logger is built for remote deployments and reliable performance in extreme conditions. It can connect up to 4 digital temperature cables and can monitor up to 125 sensors. This temperature data logger has an enhanced solar power battery so you can collect long-term data. In addition, the datalogger is designed with Iridium satellite link and Bluetooth for your connectivity of choice.


The D605 data logger architecture allows for full flexibility to expand sensor interfaces and additional peripherals such as extra memory and data transmitting options (future developments).


4 plug and play Digital Temperature Cable (DTC) ports connect up to 500 sensors

Capacity for over 10 million samples

Pre-installed Iridium embedded two-way satellite data transceiver with integrated Iridium antenna can transmit data from any location worldwide.

3.5 watt solar panel with temperature compensated charge control circuit to protect and prolong battery life.
