Hobo - Model UX120-018 -Plug Load Data Logger

Accurate and Rugged

The UL certified logger provides 0.5% measurement accuracy with a measurement resolution of 1 watt, making it an ideal choice for building audits where detailed energy use data is required. The rugged housing is designed to withstand the rigors of real-world handling, providing reliable performance despite bumps, drops, and use under desks.

Key Advantages

• 0.5% measurement accuracy enables more reliable plug load energy data
• "Meter Mode" provides instant viewing of real-time plug load variables
• Large memory enables faster logging intervals for more comprehensive plug load profiles
• Battery back-up ensures logged data remains intact in the event of a power outage or load failure
• Full-featured LCD display provides visual diagnostics for easy deployment
• Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis

• Calibration: This device has been calibrated using equipment that has been tested in accordance with ANSI C12.20 0.5%. To maintain maximum accuracy, recalibration should be performed after 1 year of use to remove the accumulated drift, which could be as much as 0.5%. After initial 1-year calibration, calibration should be performed every 3 years. Contact Onset Technical Support at loggerhelp@onsetcomp.com when recalibration is required.
