The HOBO MX100 Temp logger measures temperature in indoor environments. With an IP67
environmental rating, the logger can be deployed in indoor locations where moisture may
form. This Bluetooth® Low Energy‐enabled logger is designed for wireless communication with
a mobile device. Using the HOBOmobile® or HOBOconnect® app, you can easily configure the
logger, read it out, and view data on your phone or tablet, or automatically upload the data to
HOBOlink® for further analysis. The logger has a built‐in alarm you can configure to trip at
thresholds you specify. Designed with a non‐replaceable lithium battery, this logger also has a
power‐saving mode that allows you to use the Bluetooth signal only when needed to maximize
battery life. Note: This logger is not supported by the HOBO MX Gateway. Contact Onset
Technical Support for questions on MX100 logger compatibility with the gateway.
