HOBO 4-Channel Pulse Data Logger - IC-UX120-017M

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 calulate 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, graphing and analysis.
