The HOBO UX120-006M Analog Data Logger is a high-performance, LCD display data logger for building performance monitoring applications.
As Onset’s highest-accuracy data logger, it provides twice the accuracy of previous models, a deployment-friendly LCD, and flexible support up to four external sensors for measuring temperature, current, CO2, voltage, and more.
The data logger is ideal for energy audits, building commissioning studies, equipment scheduling, and more.
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.
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.
Monitor energy and industrial equipment with this 15-channel data logger (Part # H22-001). With multiple channels, energy and facility managers can quickly and easily detect and address a variety of issues relating to HVAC, machinery, and other systems. The HOBO H22-001 Energy Data Logger is modular and more economic than its alternatives because a toolbox full of data loggers is not necessary.
Deploy this product with a variety of pre-defined plug-and-play smart sensors to create a robust monitoring system. Compatible with HOBOware® software, researchers can conduct effective data analysis in minutes.
The HOBO MX1105 multi-channel data logger, with four-channel inputs, measures and transmits data wirelessly from a variety of sensors to your mobile device via Bluetooth technology.
This self-contained wireless data logger lets you use your mobile device or Windows computer and Onset’s free HOBOconnect app to access data, at any time, over a 100-foot range via Bluetooth. You can configure the logger, read out data, view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files – all with no dedicated equipment beyond a mobile device. And if used with the new MX Gateway, you can remotely access your data in Onset’s cloud-based HOBOlink® software. The MX1105 is ideal for energy audits, building commissioning studies, equipment scheduling, and more.

Rope CTs are excellent for bus-bars and large switch-gear applications. Self-powered rope CTs are flexible and easy to install, but will not be accurate below 30A. Each CT includes the two-pin CT connector plug.
Split-core CTs from J&D Sensing offer a well constructed hinged body and are accurate to +/-1% from 1%-100% of their stated current rating. The small interval for physical size options (10mm/0.39", 24mm/0.94", and 36mm/1.42") allow for a flexible installation. Each CT size has a hinge and clipping mechanism, making it easy to close the CT in tight situations.
The EG4115 Core is a 15-channel energy meter with 0.5% revenue-grade accuracy compliance and the ability to measure residential or commercial circuit panels, up to 3-phase 277/480VAC and 6900A. The meter has HomePlug AV powerline communication, an Ethernet port, and 2 USB ports for additional options, like WiFi. The embedded web server lets you connect to the interface over the internet or on a local area network. Each unit has a data logger that stores up to 64 data points for the lifetime of the hardware, and you can access data as granular as 1-second averages for the most recent hour of recording. The EG4115 Core is an accurate and flexible solution for monitoring multiple circuits in any residential or commercial energy monitoring application.
