Measuring and control technology also ensures efficiency in air conditioning and ventilation technology: the testo 6321 high-precision pressure transmitter for measuring differential pressure has long-term stability and helps you to monitor and control processes in air conditioning, ventilation and cleanroom technology in a reliable and efficient way.

With the testo 6383, you get a differential pressure transmitter in a cleanroom-compliant panel design. In addition to differential pressure, the transmitter also offers humidity and temperature recording (with an optional probe).
