Pulse Input Data Logger

Description

The HOBO UX120 Pulse Data 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 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.

Environment:
The UX120-017 Data Logger is for use inIndoor environments

Measurements:
The UX120-017 Data Logger supports the following measurements (sensors sold separately):

State, Event, Runtime or Pulses from a variety of sensors including energy and flow meters.
