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

Testo · testo 6614
The testo 6614 temperature and humidity probe is designed for measurements in processes that are difficult to access. With its integrated sensor heating, the humidity sensor is optimally protected against condensation and corrosion – so you can enjoy high-precision measurement results, even with high process humidity, and benefit from its long service life.

Testo · testo 6615
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.

Testo · testo 6617
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.

Testo · testo 6631
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.

Testo · Capuchon de protection en PTFE avec orifice de purge
The protective cap made of PTFE prevents damage to the sensor system caused by humidity or moisture in processes with high humidity. Thanks to the drip hole, the condensate can drain off. Optimum protection is provided by the protective cap in combination with our condensation protector.

Testo · Capuchon de protection plastique
The open plastic protection cap protects the sensor mechanically from damage by touching.

Testo · Filtre de protection métallique, Ø 12 mm
The open metal protection cap protects the sensor mechanically from damage by touching.

Testo · Filtre en acier inoxydable fritté
With the sintered stainless steel filter, you protect your sensor reliably from dirt particles – even in applications in dusty atmospheres or at higher flow velocities.
