HOBO® Temp Data Logger (UX100-001) Manual 

The HOBO Temp data logger records temperature in indoor environments with its integrated 
sensor. Using HOBOware®, you can easily configure the logger alarm to trip for specific high or 
low temperatures. Or, you can set up burst logging in which the logger records data at a different 
interval during certain conditions. The logger can also calculate minimum, maximum, average, and 
standard deviation statistics. This compact data logger has a built-in LCD screen to monitor 
temperature, logging status, battery use, and memory consumption in between readouts.
