HOBO® MX100 Temp Logger Manual
20813-J
The HOBO MX100 Temp logger measures temperature in indoor environments. With an IP67
environmental rating, the logger can be deployed indoors where moisture may form. This
Bluetooth® Low Energy (BLE)-enabled logger is designed for wireless communication with a
phone, tablet, or computer. Using the HOBOconnect® app, you can easily configure the logger
and then download logged data to view or export it 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
