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

The HOBO UX120 Pulse Logger is a highly versatile, 4-channel energy data 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 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.

The UX120-017M Data Logger is for use in Indoor environments

The UX120-017M Data Logger supports the following measurements (sensors sold separately): AC Current, AC Voltage, Amp Hour (Ah), Amps (A), Event, Kilowatt Hours (kWh), Kilowatts (kW), Motor On/Off, Power Factor (PF), Pulse Input, Runtime, State Open/Closed, Volt-Amp Reactive (VAR), Volt-Amp Reactive Hour (VARh), Volt-Amps (VA), Volts (V), Watt Hours (Wh), Watts (W)
