Air Monitor’s high-accuracy differential pressure transmitters and flow stations will help optimize the performance of your commercial HVAC system. Air Monitor transmitters are equipped with an auto-zero feature that will eliminate the zero-drift that occurs in transducers over time. With accuracies that range from 0.5% to 0.1%, Air Monitor transmitters are suitable for all applications, from commercial HVAC systems to high-accuracy laboratory systems. Complete your airflow measurement station by pairing our differential pressure transmitters with our industry-leading pitot tube technologies. Air Monitor pitot tube stations have the shortest straight run requirements in the industry and use the Feicheimer method to measure true static pressure. Our VOLU-probe stations have AMCA-certified accuracy. Air Monitor differential pressure transmitters, combined with VOLU-probe and FAN-E flow stations, achieve the highest accuracy measurement in supply ducts, return ducts, fan inlets, VAV boxes, and dampers.
