Differential pressure transmitter with humidity/temperature option

Differential pressure transmitter in cleanroom-conform panel design

testo 6651 humidity/temperature transmitter for critical climate, accuracy up to ±1.7 %RH (depends on the probe), selectable signal outputs, optional display, optional ethernet module, optional relay, 2 analog outputs

The testo 6681 temperature and humidity transmitter is designed for monitoring critical climate in industrial processes (e.g. production/process engineering). If these involve maximum precision or specialized applications (high humidity, trace humidity, etc.), then this climate transmitter is the ideal choice because, when it comes to humidity measurement, it features unrivalled cutting-edge technology.

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.
