The testo 6602 temperature and humidity probe is designed for measurements in air conditioning ducts.

The testo 6603 temperature and humidity probe is designed for measurements in air conditioning ducts, is equipped with a high-precision, long-term stable humidity sensor from Testo and delivers precise measurement results.

The testo 6604 temperature and humidity probe is designed for measurements in processes that are difficult to access.

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 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 wall and duct bracket is the ideal solution for securely mounting the testo 66xx humidity probes. Use the bracket for either wall or duct mounting of the probe.
