HOBO® 4-Channel Analog Data Logger (UX120-006M) Manual
The HOBO 4-Channel Analog data logger has 16-bit resolution and can record up to 1.9 million
measurements or events. The four external channels accept a variety of sensors, including
temperature and split-core AC current sensors as well as 4-20 mA and voltage input cables (sold
separately). Using HOBOware®, you can easily configure an alarm to trip when the sensor
reading rises above or falls below a measurement that you specify. 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
easy-to-use data logger has a built-in LCD screen to check current readings and to monitor
logging status, battery use, and memory consumption in between readouts.
