Onset UX120 Specifications

HOBO® UX120 Plug Load Logger

Measures power and energy consumption of 120V ofce equipment plug loads

Onset’s HOBO Plug Load Logger is a high-accuracy, easy-to­deploy data logger that measures and records the power and
energy consumption of 120V plug loads from office equipment,
vending machines, and other devices.

The 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.

Supported Measurements: AC Current, AC Voltage, Amps,

Kilowatt Hours, Power Factor, Volt-Amps, Volts, Watt Hours,
Watts

Key Advantages:

• 0.5% measurement accuracy enables more reliable plug load energy use 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

• Factory calibrated (see user’s manual for details)

Minimum System Requirements:

Software USB cable*
