Stability is defined as a change (or lack of change) in accuracy over a period of time.
Drift is commonly used as a specification to illustrate the stability, or change in accuracy over a period of time, commonly shown as X%/year where X = a number; i.e. 0.25%/year. In this scenario, a device with a ±1% accuracy, would be expected to have an accuracy of ±1.25% (1%+0.25%) after a period of one year. Depending on the design, brand, and range of the sensing instrument, the stability can vary widely. Continue reading “What is Stability and Why is it Important?”
The Series SAH SMART Air Hood® balancing instrument looks different than traditional air hoods, but that’s because it’s solving balancers’ problems in a new way. Take, for example, some feedback we received from Ken (a TAB technician) earlier this year.
Small, highly maneuverable air hood Ken was measuring standard 2’ x 2’ diffusers with our SMART Air Hood® balancing instrument and the new app. While taking measurements, he ran into an area with very little clearance. Continue reading “Air Balancing Success Story”
The current COVID-19 pandemic spread and breadth is unprecedented. Because of this, it is important that precautions are taken when reopening schools and office buildings. The question we find ourselves asking as professionals in the HVAC trade is this:
