This 4-channel energy data logger UX120 combines the functionality of four separate data loggers into one compact unit. It enables energy management professionals -- from energy auditors to building commissioners -- to easily track building energy consumption, equipment runtimes, and water and gas flow rates.

Simultaneously measures and records pulse signals, events, state changes, and runtimes
Capable of 500,000 measurements (over 4 million with expanded memory version), enabling longer deployments with fewer site visits
Maximum pulse rate – 120 Hz
Pulse input range – 0 to 24VDC
Streamlines deployment via a range of start/stop options, logger status LEDs, and high-speed USB 2.0 data offload
Works with Onset's Energy & Power Meter T-VER-E50B2 to measure Power Factor (PF), Reactive Power (VAR), Watt Hours (Wh) and more.
