Monitoring critical environments - such as cleanrooms, operating rooms, and compounding pharmacies - is paramount to maintain safety and remain compliant with regulatory standards. In these critical spaces, it is often required to monitor multiple environmental parameters.

For decades, hot-wire anemometers have been widely used throughout hospitals to ensure proper pressurization in critical spaces such as operating rooms and isolation rooms.

Inhaling airborne particles can put both critical patients and healthcare staff at risk for detrimental health issues. Controlling these particles is necessary for protecting both staff and occupants of nearby rooms from exposure to infectious particles. To maintain safety in a hospital, it is crucial to monitor both differential pressure and particle counts in anterooms.

Critical environments can have a variety of layouts depending on the purpose of the space. Frequently, these critical environments will have a multi-room setup. Some examples of a multi-room setup are an isolation room and anteroom or a cleanroom, gown up room, and clean storage area.

Hot-wire anemometers are widely used throughout hospitals. Although their initial accuracy remains undisputed, a hot-wire anemometer's accuracy is not stable over time. Hot-wire anemometers must be cleaned at regular intervals to remain an accurate and effective solution for monitoring room pressure. Without regular cleaning and calibration, the accuracy of a hot-wire anemometer decreases significantly over time.
