Onset's HOBO Plug Load Data Logger is a high-accuracy, easy-to-deploy data logger that measures and records the power and energy consumption of 120V plug loads from office equipment, vending machines, and other devices. Accurate and Rugged The UL certified logger provides 0.5% measurement accuracy with a measurement resolution of 1 watt, making it an ideal choice for building audits where detailed energy use data is required. The rugged housing is designed to withstand the rigors of real-world handling, providing reliable performance despite bumps, drops, and use under desks.
Note: The UX120-018 logger is intended for use on 15 AMP circuits (NEMA 5-15P) with a working voltage of 120V AC ±10% at 50/60Hz and a max power of 1800W.
