Differential pressure between two rooms prevents dust, particulates, and pathogens from entering or exiting one room and going into the other. Depending on the relationship between rooms, one room will be under positive pressure when referenced against the other. This positive-negative pressure relationship between two spaces is the main idea behind clean rooms and isolation rooms. To ensure the differential pressure relationship is maintained, a measuring device must be used.
Room pressure monitors and room status monitors measure, display, and transmit the differential pressure reading between two rooms. In general, room pressure monitors only monitor differential pressure. On the other hand, room status monitors monitor differential pressure and additional parameters such as relative humidity, temperature, air change, or door status. They are both used in critical applications that require critical low differential pressure relationships. Continue reading “What are Room Pressure and Room Status Monitors?”
The purpose of a clean room is to limit the number of particulates in a clean space. These particulates can be any type of sub-micron particles, such as dust, pathogens, chemical vapors, or moisture droplets. Clean room manufacturing areas are used by many industries to produce semiconductors, pharmaceuticals, medical devices, etc.
In this age of virtual meetings and online connections, to “Google” something has become synonymous with quickly looking up information. For some, bookshelves are more for decor than they are functional, and trends are leading to becoming more environmentally-friendly and saving paper. Print media is not necessarily “dead,” but it is becoming much less prevalent as we journey forward in this digital age.
