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 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.

The testo 6605 temperature and humidity probe is equipped with a high-precision, long-term stable humidity sensor from Testo and delivers precise measurement results.

The testo 6612 temperature and humidity probe is designed for measurements in air conditioning ducts.

The testo 6613 temperature and humidity probe is designed for measurements in processes that are difficult to access.

The testo 6615 temperature and humidity probe is designed for measurements in trace humidity applications. The automatic self-adjustment procedure corrects the measurement uncertainties that traditionally occur when measuring humidity in the lowest humidity ranges - so you benefit from extremely accurate measurement results.

The testo 6617 temperature and humidity probe is designed for measurements in environments with aggressive media. With the built-in self-monitoring function, you can prevent faulty measurements or measurement interruptions – because it detects signs of corrosion at an early stage, thus the probe can be replaced in good time.

The pressure-tight screw connection (stainless steel) with G1/2" thread and PTFE ring is ideal for mounting your temperature and humidity probe in the process. The PTFE clamping ring enables quick mounting and holds the probe securely in place, and can be removed without leaving any residue after use.
