TidbiT MX External Temp Data Logger

A waterproof data logger with both an internal sensor and an external sensor that’s designed for monitoring fast-changing temperatures; can be deployed just above water or soil, for the most convenient wireless data download to your mobile device or laptop.

External Temp Data Logger

Overview

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 our 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.

Purchase an MX Data Plan to get more out of your data and access it from anywhere using the LI-COR Cloud software platform (formerly HOBOlink)! You can also purchase the MX Gateway station, which automatically sends your logger’s data to LI-COR Cloud.
