Overview
A highly versatile, 4-channel energy data logger that combines the functionality of four separate loggers into one compact unit. Enables energy management professionals, from energy auditors to building commissioners, to easily track building energy consumption, equipment runtimes, and water and gas flow rates. This logger has a standard memory capable of 500,000 measurements, and is also available in an expanded memory version, the HOBO UX120-017M, capable of over 4,000,000 measurements.
Features
- 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's Energy & Power Meter to measure Power Factor (PF), Reactive Power (VAR), Watt Hours (Wh) and more. Learn how. The T-VER-E50B2 Energy and Power Meter outputs (3) sets of pulses which are logged by the UX120-017. These pulses represent Watt-hours, Amp-hours, and VAR-hours. HOBOware software uses these pulse values to calculate AC Current, AC Voltage, kW, Power Factor, VARs, and VA. The formulas used in these calculations can be found here: 14993-A-Derived-Channels.zip
- Compatible with HOBOware and HOBOware Pro software for logger setup and graphing & analysis
