The Testo 6321 differential pressure transmitter provides excellent performance at an affordable price for automated air conditioning and ventilation applications. Because automated building processes necessitate precision monitoring, heavy demands are placed on the monitoring equipment. The Testo 6321 differential pressure transmitter fulfills these requirements by ensuring excellent system functionality. When climate conditions are optimized by highly accurate measurement systems and creating long-term differential pressure stability, the result is energy savings. Like all Testo transmitters, the Testo 6321 differential pressure transmitter features P2A software. The analysis tools incorporated in the software test analog and relay signals and display min/max values. The transmitter software also includes an operational hour counter which means reports are stored with a time/date stamp to provide a history of error events.
