Video-inspection system

Designed for numerous HVACR applications — such as detecting leaks, inspecting corrosion and deposit buildup, and reading hidden part and serial numbers — the Seeker 100 Wireless USB Video Inspection System includes the RCV100 USB Video Receiver, which wirelessly connects the inspection system to Windows, enabling video to be viewed on a computer or streamed live over the Internet via Skype. The range of the wireless connection is 9.8 ft. Video can be captured, recorded, or edited using the computer's internal software or third-party video-editing software. The inspection system offers a way to inspect inaccessible or hazardous areas and diagnose hidden system problems without complete disassembly or teardown.

Oxygen sensor

Developed as a reliable sensor for the HVAC industry, the Dynamic Oxygen Sensor has an oxygen-measurement range of 0.5 to 100 percent. No reference atmosphere or consumable materials are required. With single-point calibration, the sensor features a high maximum operating temperature of 1,382°F and high temperature stability. Also, the sensor is not susceptible to poisoning by high carbon-dioxide levels. The technology offers many possible sensor configurations, ranging from a discrete element to a fully packaged sensor system with signal-processing electronics.

Data-loggers guide

A 24-page guide from Onset, “Monitoring HVAC Performance With Data Loggers” describes how data loggers provide unbiased evidence of system operations and can help locate the source of comfort problems, diagnose HVAC-equipment operation, identify potential energy-efficiency upgrades, verify savings, and contribute to Leadership in Energy and Environmental Design certification. The guide provides an introduction to assessing and diagnosing common comfort, environmental quality, and mechanical problems. The guide also discusses retrocommissioning, the types of data loggers available, and how to choose a data logger.

Smart meters

PowerLogic PM1200 multifunction power meters and DM6200 digital panel meters provide commercial and industrial facilities with a simplified metering solution that monitors energy use, helping users make choices about power consumption and efficiency. The meters maximize use of existing power infrastructures by providing accurate data that helps facility managers and consumers identify areas for energy savings. The DM6200 is used for equipment monitoring and preventive-maintenance scheduling and provides basic electrical values, such as volts, amps, frequency, and power factor. In addition to reporting the same measurements as the DM6200, the PM1200 measures power, energy demand, and total harmonic distortion and is best utilized for energy, power, and demand monitoring; load studies and circuit optimization; energy balancing; and energy optimization.

Humidity sensors

For applications with stringent accuracy requirements, SHT25 high-precision digital humidity and temperature sensors measure relative humidity (RH) from 0 to 100 percent and temperature from -40°F to 257°F. The sensors achieve a typical accuracy of 1.8-percent RH and ±32.36°F. Typical tolerance is small, even at the limits of the measuring range. The maximum tolerance is 2-percent RH or 3±2.54°F. Additional features include a comprehensive quality-management system and individual sensor-tracking data.
