The HOBO TidbiT MX2205 is ideal for monitoring shallow waters, like streams and wetlands, or for monitoring soil in fields that are prone to flooding. Equipped with both an internal sensor to monitor ambient temperature and an external sensor on a 2m cable to accurately monitor fast-changing temperatures, the HOBO TidbiT Mx2205 is a low-cost, easy-to-use, waterproof logger that leverages the power of Bluetooth to deliver high-accuracy data straight to your mobile device or Windows laptop running Onset’s free HOBOconnect app. This rugged logger withstands harsh environments, and can be deployed just above water or soil for quicker, more convenient data downloads that don’t require pulling up the logger.
