Why are Dwyer® sensors used to improve indoor air quality?

In a new report provided by the Lancet COVID-19 Commission Task Force experts have identified “four key actions that represent the most effective, fundamental steps toward promoting healthier indoor environments and reducing the risk of airborne infectious disease transmission indoor[s].”

Where are Dwyer® sensors used to improve indoor air quality?

Dwyer Instruments is the premiere manufacturer and innovator of sensors that make up the heating, cooling, and ventilation system found in our daily lives. Dwyer® sensors can be found in schools, hospitals, office spaces, data centers, transportation terminals, or parking and warehousing locations. Where there is an HVAC system present, Dwyer® products can be used to help it run.



Dwyer® gages and room status monitors are used in hospital isolation rooms or operating rooms to provide reliable and accurate monitoring of pressure levels. Maintaining negative pressure in isolation rooms helps to keep contagions within that space and away from other patients or medical staff. The opposite is true for operating rooms; maintaining a positive pressure within the room keeps the area sterile for safe medical procedures.

Our transmitters are used in schools and offices as a reliable and accurate way to monitor carbon dioxide (CO2) levels. Keeping CO2 levels in a safe range can lead to both improved cognitive responses for the people in the buildings, as well as reduction of energy consumption for the building system itself.

Offices & Airport Terminals

Our Magnesense® differential pressure transmitters and Magnehelic® gages are found in air handling units that condition the air in offices and airport terminals. Changing the filter when the differential pressure reads high will help keep the system running at maximum efficiency for cleaner, breathable air.

Dwyer’s transmitters are used in parking garages and warehouse spaces to monitor carbon monoxide (CO) and nitrogen dioxide (NO2) levels to prevent illness and control exhaust fans. By monitoring CO or NO2 and running an exhaust fan as needed, building owners can reduce their carbon footprint and ensure the safety of occupants.

Dwyer’s Series IEF electromagnetic flowmeters are key to ensuring the smooth running of the critical cooling systems. The ability to change the sensor while not interrupting the operation of the chillers is a major advantage of the IEF. Additionally, Dwyer can offer a unique option that allows three IEF’s to be positioned in the same location in one pipe and provide safety redundancy for the operation of cooling circuits. Dwyer has a full range of humidity, temperature, differential pressure, and velocity sensors to control the environment inside data centers.

Clean Rooms & Critical Environments

Clean rooms require precise and accurate measurement of the differential pressure within a contained environment. Dwyer’s extensive range of low differential pressure transmitters and room status monitors allow for precise control of this critical measurement. The Dwyer Instruments range of clean room sensors offers the correct technology and accuracy to match the end user’s needs, ensuring compliance with regulations.
