HOBO TidbiT MX Temp loggers measure temperature in streams, lakes, oceans, coastal
habitats, and soil environments. Housed in a protective boot, these rugged loggers are
designed for extended deployments in fresh or salt water at depths up to 400 ft (MX2203) or
5,000 ft (MX2204). The loggers use Bluetooth® Low Energy (BLE) for wireless communication
with a phone, tablet, or computer, and are equipped with an optional water detection feature
that automatically turns Bluetooth advertising off when the logger is submerged in water,
preserving battery power. Using the HOBOconnect® app, you can easily configure the loggers,
download logged data to your mobile device or computer, or automatically upload the data to
HOBOlink® for further analysis. You can also configure the loggers to calculate statistics, set up
alarms to trip at specific thresholds, or enable burst logging in which data is logged at a faster
interval when sensor readings are above or below certain limits.

Water conductivity level of 100 µS/cm or greater necessary for reliable
detection of water. Deionized water or water below 100 µS/cm may
not be detected.
The water conductivity circuit may not reliably detect water that has
frozen around the electrodes, i.e., below 0°C (32°F).

Faster logging intervals and statistics sampling intervals, burst logging,
remaining connected with the app, excessive downloads, and paging
may affect battery life.
