Question: I am looking to use a flowmeter calibrated for air to monitor CO2 flow. Are there any concerns or correction factors I need to apply?
Question: Is there a kit I can buy with the Magnehelic® Differential Pressure Gage for monitoring air filters, so that I don’t have to buy all the tubing, static pressure tips, and a bracket separately?
Question: Does Dwyer offer a differential pressure switch with manual reset for high duct static cutout applications?
Dwyer offers several carbon dioxide measuring products that use non-dispersive infrared sensors as the sensing element. Carbon dioxide sensors are commonly used in building automation systems to monitor air quality. The level of carbon dioxide is indirectly proportional to the amount of people in a space and can be used to adjust ventilation for the space.
There are two basic types of gas sensing technologies: chemical reaction and infrared spectroscopic. Most chemical reaction sensors are electrochemical sensors, which are not as reliable as they can interact with multiple gases and wear from interaction with the gas.

How will the installation of a Magnehelic® Differential Pressure Gage 150 feet away from the pressure source affect accuracy?
