Energy measurement tools help determine energy uses and trends within a building. Analyzing these energy systems and behaviors assist in designing more efficient energy and power systems, bench-marking the performance of existing systems, and detecting any faults and anomalies within current systems. Proper energy management will help reduce a building’s Energy Usage Index (EUI), and reduce utility bills.

HOBO Plug Load Data Logger

plug load, kWh

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 rugged housing is designed to withstand the rigors of real-world handling, providing reliable performance despite bumps, drops, and use under desks.
Logging Rate: 1 second to 18 hours, 12 minutes, 15 seconds

Sensor Range (Accuracy): 
Logging: 5° to 40°C (41° to 104°F); 0 to 95% RH (non-condensing), up to 2,000 m (6,562 ft) altitude 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.

Dwyer Portable Analog Signal Generator

Troubleshooting transmitters, transducers and actuators.

The Model ASG is a handheld analog signal generator. It generates a 0-10 VDC signal in increments of 1V or a 0-20 mA signal in increments of 2 mA. The LED bar graph visually indicates analog signal level. It can also continuously ramp to user-defined minimum or maximum values with user-defined ramp-time settings. See attachment for additional information.

Sensor Range (Accuracy): 
Current- 0.5% FS or 0.1 mA Voltage- 0.5% FS or 0.05 VDC Current-2mA Voltage-1VDC

Circuit Breaker Finder

This Automatic Circuit Identifier comes with a digital receiver and a 120-volt-240-volt GFCI receptacle tester. Now you have a unit that automatically indicates the right breaker for quick and easy breaker identification and plus verifies the presence of power. It works on 120-volt-240-volt circuits. A noncontact voltage sensor is included. The GFCI receptacle tester is a part of this kit as well and verifies proper wiring. See attachments for additional information.


WattNode Pulse Output kWh Transducer

The WattNode offers precision energy and power measurements. The WattNode enables you to make precise power and energy measurements from within existing electric service panels. The WattNode is designed for use in demand side management (DSM), sub-metering, and energy monitoring applications. The WattNode outputs a stream of pulses whose frequency is proportional to the instantaneous power and whose count is proportional to total watt-hours. See attachments for additional information.
