Onset’s HOBO UX120-006M Analog Logger provides a deployment-friendly LCD and support for up to four external sensors for measuring temperature, current, CO2, voltage and more. It visually confirms logger operation and battery status. As the logger records, the LCD provides a near real-time readout of the current measurements as well as minimum, maximum, average and standard deviation statistics. It is capable of storing 1.9 million measurements. On-screen alarms can be set for each channel to notify users when a sensor reading exceeds high or low thresholds.
