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.

The testo 6351 pressure transmitter for differential pressure is suitable for industrial applications. It can record even the lowest pressures with a high level of accuracy. The pressure transmitter was specially designed for monitoring differential pressure in the 50 Pa to 2,000 hPa measuring range.

The testo 6381 pressure transmitter for differential pressure offers the advantage of being able to calculate volume flow and flow velocity as well. With an optional probe, the transmitter also enables temperature and humidity measurements.

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).

The high-performance measurement transmitter testo 6621 is a reliable partner for applications in building air conditioning. Accuracy, long-term stability and reliability – our measurement transmitter meets the high demands of building automation, helping you to reduce costs.

The testo 6631 temperature and humidity transmitter is designed for use in greenhouses and laboratories. Use the transmitter for reliable monitoring of critical climates in biological research.

The testo 6651 transmitter for demanding measuring tasks: In combination with the testo 660x probe series, the transmitter can master exceptionally demanding measuring tasks in air conditioning technology and numerous other fields of application.

Ideal for industrial humidity measurement: With professional measuring technology, maximum precision and practical features, the testo 6681 humidity transmitter, in combination with the testo 6610 probe series, is impressive even when it comes to demanding measuring tasks, e.g. in drying and air conditioning technology, high humidity or trace humidity applications.

With the P2A software, the (suitable) Testo measurement transmitter can be especially easily parameterized, adjusted and analyzed. Thanks to the adapter included in delivery, you can immediately connect the measurement transmitter to your PC.
