The HOBO UX120-006M Analog Logger is a high-performance (16-bit), LCD display data logger for building performance monitoring applications.

As Onset’s highest-accuracy data logger, it provides twice the accuracy of previous models, a deployment-friendly LCD, and flexible support up to four external sensors for measuring temperature, current, CO2, voltage and more.

The logger is ideal for energy audits, building commissioning studies, equipment scheduling, and more.

  • Twice the accuracy over previous models with 16-bit resolution
  • Flexible support for a wide range of external sensors
  • LCD confirms logger operation and displays near real-time measurement data
  • Provides minimum, maximum, average and standard deviation logging options
  • On-screen alarms notify you when a sensor reading exceeds set thresholds
  • Stores 1.9 million measurements for longer deployments between offloads

The UX120-006M Data Logger is for use in Indoor environments

The UX120-006M Data Logger supports the following measurements (some sensors sold separately):

Temperature, 4-20mA, AC Current, AC Voltage, Air Velocity, Carbon Dioxide
IMPORTANT: HOBO data loggers require HOBOware software (USB interface cable included w/CD purchase). See compatible items above.
