IMPORTANT:data loggers require software (USB interface cable included w/CD purchase) and a communications device. See compatible items below.

The HOBO UX120 Pulse Logger is a highly versatile, 4-channelenergydata logger that 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. The HOBO UX120 Pulse Logger is available in astandard memory model (UX120-017)capable of 500,000 measurements and anexpanded memory version (UX120-017M)capable of over 4,000,000 measurements.

• Simultaneously measures and records pulse signals, events, state changes, and runtimes
• Stores up to over 4 million measurements, 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'sEnergy & Power Meterto measure Power Factor (PF), Reactive Power (VAR), Watt Hours (Wh) and more.
