The steps of a commercial building roof moisture survey

Roofs are meant to keep moisture out and conditioned air in. But holes and leaks can develop over time, and water intrusion poses a great threat to every building. To top it off, moisture doesn’t just come from rain. HVAC systems, condensation, plumbing leaks, and…

3D snapshot sensor for 3D measurements and surface inspection of large objects

Large, diffuse reflecting objects of up to 650 x 495 mm are measured using the surfaceCONTROL 3D 2500 snapshot sensor. The sensor is based on the fringe light projection principle to perform geometrical 3D measurements and 3D shape detection, as well as surface inspections. It can be used both withi Source: Micro-epsilon…

How a commercial energy audit could save you money

Owning and maintaining commercial real estate is costly. Whether it’s an office building, retail space, or something else, it’s your responsibility as a building owner to ensure it remains comfortable, safe, and up to code. And all too often, those responsibilities equate to high commercial…

The irony of the magnet system for Kibble balances—a review

The magnet system is an essential component of the Kibble balance, a device that is used to realize the unit of mass. It is the source of the magnetic flux, and its importance is captured in the geometric factor Bl . Ironically, the Bl factor cancels out and does not appear in the final Kibble equation. Nevertheless, care must be taken to design and build the magnet system because the cancellation is perfect only if the Bl is the same in…

Achievement of 0.005% combined transfer uncertainties in the NIST detector calibration facility

Improvements in a lamp-monochromator-based facility at the National Institute of Standards and Technology (NIST), the Visible near-infrared Spectral Comparator Facility (VisSCF) which is used to calibrate optical detectors for spectral radiant power responsivity from 300 nm to 1100 nm, are described. These changes include extending the VisSCF operational range down to 300 nm from 350 nm, thereby fully covering the ultraviolet-A (UVA) spectral region and partially covering the UVB range. These improvements have lowered the magnitudes of most of the components in the uncertainty budget…

Spectral irradiance scale realization and uncertainty analysis based on a 14 mm diameter WC–C fixed point blackbody from 250 nm to 2500 nm

Spectral irradiance scale in the wavelength range from 250 nm to 2500 nm was realized at National Institute of Metrology on the basis of a large area tungsten carbide–carbon (WC–C) high temperature fixed point blackbody, which is composed of a 14 mm diameter WC–C fixed point cell and a variable temperature blackbody BB3500MP as a furnace. A series of 1000 W FEL tungsten halogen lamps were used as transfer standards. The new spectral irradiance scale was compared with the scale based on a variable-temperature blackbody…

Is your crawl space costing you?

More than 1 in 10 homes in the United States have a crawl space: a small area under the house that separates it from the ground. Most crawl spaces are vented, which means that air exchanges freely with the outside. Ductwork, water pipes, gas lines,…
