Decoding Humidity Accuracy

Considering humidity accuracy measurements is necessary when selecting a relative humidity transmitter. Accuracy, by definition, is "the degree to which the result of a measurement, calculation, or specification conforms to the correct value or standard" (Oxford English Dictionary). When comparing accuracy measurements of different relative humidity sensors, understanding the factors included in said measurements is crucial. An accuracy measurement should consist of non-linearity, hysteresis, repeatability, and calibration uncertainty. These factors can be defined as:

Preparing for The Joint Commission Visits

The Joint Commission (TJC) is a non-profit organization dedicated to ensuring hospitals and other medical facilities provide safe, high-quality care to patients. TJC accredits healthcare organizations throughout the United States. Accreditation occurs every 3 years, but inspection surveys occur unannounced every 18 to 39 months, taking between 2 and 3 days to complete. For most of the United States, Medicare and Medicaid funding depend on TJC accreditation.

Building Automation and Energy Management

Building automation systems (BAS) are increasingly common in a variety of environments to make HVAC systems as efficient as possible and reduce the need for in-person monitoring of pressure in each area. The value of a BAS relies heavily on a number of components seamlessly integrated together. Pressure transducers that conduct intensely accurate measurements work in tandem with room pressure monitors presenting real-time data and raising alarms if something goes wrong. Calibration equipment ensures building automation tools work smoothly and accurately without the need to oversee them. A BAS can be used in many applications, from filter monitoring to green buildings to zone control in critical environments.

The Importance of Counting 2.5um Particles in Hospital Operating Rooms

Nosocomial infections (also known as Hospital-Acquired Infections, Healthcare-Associated Infections, or HAIs) can result in otherwise avoidable extended hospital stays, readmittance, follow-up treatments, and even death. HAIs can often spread via airborne transmission, which emphasizes the need for proper room pressurization to contain hazardous particles. Operating rooms (ORs) are an area where patients are especially at risk for contracting infections. 2.5µm particles are an important leading indicator of the potential presence of contaminants that could put the patient at risk. The best opportunity to manage the risk of infections is by limiting 2.5µm particles in a space.

How Many T/RH Sensors Do I Need in My Space?

Many HVAC, critical environments, and industrial applications employ temperature and relative humidity (T/RH) sensors. But exactly how many T/RH sensors does an application require? It is difficult to spec the exact requirements for certain applications for a variety of reasons. No two applications are identical, and thus no two spaces require the same number of T/RH sensors. As each application is unique, the number of sensors needed depends on several factors, including:
