HOBO UX120 Four-Channel Analog Data Logger

This data logger is ideal for use in building performance monitoring applications and accepts up to four external sensors (sold separately). The logger delivers accurate measurements, features 16-bit resolution, and stores up to 1.9 million measurements to allow for longer deployments between offloads. You can configure the on-screen alarm to activate when a sensor reading rises above or falls below a specific measurement level. Burst logging allows the logger to record data at a different interval during certain conditions. An LCD confirms logger operation and displays current measurement data, battery use, and memory consumption between readouts. In addition, the logger can calculate minimum, maximum, average, and standard deviation statistics. Requires either HOBOware (available as a free download), or HOBOware Pro software (sold separately).
