The self-contained wireless data logger, which works with Onset’s HOBOmobile app for logger setup and data management, enables you to access data anytime from mobile device for iOS or Android over a 100-foot range, and it requires no dedicated equipment beyond a mobile device for configuring the logger or reading out data. With Onset’s HOBOmobile app, you can view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files. The logger can calculate minimum, maximum, average, and standard deviation statistics and be configured to trip audible or visual alarms at thresholds you specify. The MX1101 also supports burst logging in which data is logged at a different interval when sensor readings are above or below certain limits. This compact data logger also has a built-in LCD screen to display the current temperature, relative humidity, logging status, battery use, memory consumption, and more.

The specified temperature range for the MX1101 logger is -20° to 70°C (-4° to 158°F). I would recommend using the UX100-014M logger with a thermocouple probe. The logger would be mounted on the outside of the freezer and only the thermocouple wire would be fed into the freezer itself. Please let me know how I can further assist you. **Q: Can the collected data be utalized by the Hoboware soft ware also??** A: You will need to download and install the HOBOmobile app in order to connect to and work with the MX1101 logger. However, you can export your data files as a HOBOware file with data, logger events, and details, includinginformation about the file and each data series. You can then mail or copy the file and open it in HOBOware. **Q: Can multiple units be used and bluetooth accessed separately in the same room to monitor conditions at different heights?** A: Hello Sean,Yes. You can configure the units and name them accordingly for your preferences.
