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

Important: this hobo data logger requires hoboware software and a communications device. See compatible items below.
The hobo ux120 pulse data logger is a highly versatile, 4-channel energydata 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 data logger is available in a standard memory model (ux120-017) capable of 500,000 measurements and an expanded 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 startstop 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 caclulate 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
