The HOBO MX water level logger is used for monitoring changing water levels in a wide
range of applications, including streams, lakes, wetlands, tidal areas, and groundwater.
This Bluetooth® Low Energy-enabled logger is designed for wireless communication with
a mobile device. Using the HOBOconnect® app, you can easily configure the logger and
read it out—all from its deployed location—to your phone or tablet where you can view
the logged data or share it for further analysis. With the app, you can also set a
reference water level and water density, configure up to 8 logging intervals, log
statistics, configure an alarm to trip at thresholds you specify, or set up burst logging in
which data is logged at a different interval when sensor readings are above or below
certain limits. This logger features a ceramic pressure sensor, durable housing, and an
integrated barometric pressure sensor for barometric compensation in the logger,
which allows for direct water level readout without needing to do any post processing.
An optional cap is also available for deployment in existing wells or stilling wells.
Without cumbersome vent tubes or desiccants to maintain and convenient data
retrieval to a phone or tablet, this easy-to-use logger is an ideal solution for water level
studies and research.
