Frequently Asked Questions
+ Show all

Can I download data from MX2200 Series loggers deployed in water?


No, the MX2200 Series need to be taken out of the water to download the data.

Do I need an optical shuttle to download data from the MX2200?


No, but you do need to have a mobile device such as a phone or tablet that runs iOS or Android operating systems and has Bluetooth 4.0 or above, or a computer running Windows 10, in order to download the data.

Is an event recorded in the data file when the logger is submersed or removed from the water?


With the MX2203 and MX2204, you have the option while configuring the loggers to select Bluetooth Off Water Detect. The logger will not advertise when the presence of water is detected. Once the logger is removed from the water, advertising will automatically turn on, thereby not requiring you to push a button (or use a magnet) to wake up the logger when you need to connect to it. This option preserves some battery power. Note: The logger will check for the presence of water every 15 seconds when this is option is selected.

Do the new MX2200 Series water loggers replace the existing Pendant and TidbiT water loggers?


No, we will continue to support the TidbiT, Pendant, and Water Temp Pro optical products, although we encourage folks to take a look at the new features of the MX2200 Series.

Can I use HOBOware software to graph, analyze, and export the data?


You have the ability to share a .HOBO file via email, or use HOBOlink.com to then open up the file in HOBOware to do additional data analysis, like combining graphs and analyzing your data further. Note that HOBOconnect can also directly output a .XLSX & .CSV file format if you choose to work in Excel.

Effortless, Accurate Data

Onset's HOBOconnect app, a free download from the Apple App Store and Google Play (or from the Onset website for your Windows computer), makes it easy to configure MX2200 Series loggers in the field and manage your data.

The loggers provide high accuracy over a wide temperature range. And the HOBO MX2202 model features a built-in light sensor to give you repeatable light-level data in shallow-water monitoring applications.


The reliable HOBO MX2200 Series loggers integrate a rich set of features in a compact, rugged package designed to streamline your deployment.
