Current Transformers (CTs) measure the amount of electricity flowing in a circuit. CTs are used with a WattNode meter, which also measures voltage.
The current and voltage measurements are used by the meter to to calculate power and energy (kW and kWh).
Standard Accuracy
Accuracy: ±0.75% from 1% to 120% of rated primary current
Phase angle: ±0.50 degrees (30 minutes) from 1% to 120% of rated current
IEEE C57.13 accuracy: class 1.2 from 1% to 120% of rated current
IEC 60044-1 accuracy: class 1.0 from 1% to 120% of rated current
Note: The ACT-0750-250 specifications apply at 120% of rated current only at temperatures of 40°C and below.

Like its name implies, the RoCoil mV produces a millivolt output for use with DENT’s ELITEpro and DATApro Series dataloggers. Available in standard lengths up to 72” and current ranges up to 6000A. The RoCoil mV requires 5-24V dc, which can be supplied from the Line-Powered ELITEpro or optional external power supply.

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.

Convert Li-Cor micro Amp out put into a voltage to supply a signal to a HOBO data logger. Output max voltage can be user seleced on the amp. The Amp should be reconfigured for use under indoor vs. outdoor environment. The max light level encountered needs to be considered with selecting max voltage out.

Fluke I410 AC/DC current clamp measures from .5A to 400 amps. Hall effect, battery powered, output 1mV per 1 amp AC or DC

The Fluke 116 was specifically designed for the HVAC professional. It has every-thing needed in an HVAC meter including temperature and microamp measurements to quickly troubleshoot problems with HVAC equipment and flame sensors.

The Logger is a modular, reconfigurable data logging system used in energy and idustrial monitoring applications. The 15-channel sustem enables the user to quickly and easily perform a broad range of monitoring applications. You can use the HOBO FlexSmart Logger with a number of Smart Sensors. It can also be sued with FlexSmart signal conditioning modules to covert signals from many types of Onset and third party sensors. HOBOware software communicates with the logger, allowing you to customize the configuration settings, download data from the Logger, and plot the data for analysis.

Four channel indoor logger.

The HOBO U12 Logger can record Temperature, Relative Humidity, and Light with 12-bit resolution and can record up to 43,000 measurements or events. The external channel accepts a variety of sensors, including temperature, and split-core AC current sensors as well as 4-20 mA

The LI-210 Photometric Sensor utilizes a filtered silicon photodiode to provide a spectral response that matches the CIE curve within ± 5% with most light sources. Some of the applications for the LI-210 Photometric Sensor include interior and industrial lighting, outdoor illuminance, passive solar energy, architecture and lighting models, illumination engineering, and biological sciences that require illuminance measurements. The LI-210 is a research grade photometric sensor that is very reasonably priced.

Current transformers, often used with the HOBO flexsmart logger. Use correnct transformer size for voltage being measured. Small then rated voltage can be measured by passing the wire throught the C/T several times. See insturction guide for details. http://www.magnelab.com/

Digital SLR camera can be used to create High Dynamic Range (HDR) images with illuminance data or for site photos.

The H600 is a current-sensitive switching device which monitors current (amperage) in the conductor passing through it. A change in amperage in the monitored conductor which crosses the switch threshold will cause the resistance of the status output to change state, similar to the action of a mechanical switch. In this model, the threshold is fixed at 150mA AC max (200mA AC for 50Hz operation). The status output is suitable for connection to building controllers, or other appropriate data acquisition equipment operating at up to 30 volts. The H600 requires no external power supply to generate its output.

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.
