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?”
Educational facilities, or public and private institutions devoted to teaching students, differ in physical size and level of education programs. These institutions can range from preschool to university levels, all of which need proper heating, ventilation, and air conditioning (HVAC) systems and indoor air quality.
While indoor air quality (IAQ) is important for everyone’s health, it is especially important for young children that are still developing their lungs. The United States Environmental Protection Agency (EPA) Science Advisory Board has completed multiple school studies that show indoor air pollution among the top five environmental risks to public health.

Commercial Refrigeration Thermostats Go Digital for Greater Control
In the past, bulb and capillary mechanical thermostats were used in chillers to maintain proper water temperature. As technology has advanced, digital temperature switches have replaced many mechanical ones because a digital temperature switch provides the same functions while also serving as a timer, external relay and thermometer. Where are digital temperature switches used, and which features have caused the conversion? Continue reading “Digital Chiller Thermostats”
