Use the alarm module in conjunction with an alarm relay to receive a visual or acoustic signal.

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).

Targeted monitoring of your compressed air consumption: Carry out compressed air measurements with the testo 6451 compressed air meter to locate leaks and enable allocation based on consumption. This will enable you to create greater transparency when it comes to your compressed air consumption and reduce costs. Particularly practical: the compressed air meter is easy to install.

Targeted monitoring of your compressed air consumption: Carry out compressed air measurements with the testo 6457 compressed air meter to locate leaks and enable allocation based on consumption. This will enable you to create greater transparency when it comes to your compressed air consumption and reduce costs. Particularly practical: For large-diameter pipes (DN65-250).

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.

Use the advantages of the mains unit as a power supply for the measurement transmitter.
