HOBO® Temp/RH 3.5% Data Logger (UX100-003) Manual
The HOBO Temp/RH data logger records temperature and relative humidity (within 3.5%
accuracy) in indoor environments with its integrated sensors. Using HOBOware®, you can easily
configure the logger alarm to trip for specific high or low sensor readings. 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 the current temperature, relative
humidity, logging status, battery use, and memory consumption in between readouts.
