Testo 440 Humidity Kit with Bluetooth

The Testo 440 Humidity Kit with Bluetooth is a practical solution for measuring humidity and temperature across a wide range of indoor and controlled environments. Supplied with the testo 440 air velocity and IAQ measuring instrument and a Bluetooth humidity/temperature probe, it is well suited to checks in storage areas, HVAC ducts, cold rooms, refrigeration systems and general work environments where reliable climate monitoring is important.

A major strength of the kit is its ability to support both straightforward spot checks and more detailed climate assessment. The testo 440 offers clearly structured measurement menus for parallel humidity and temperature measurement, while also automatically calculating values such as dew point, wet bulb temperature and absolute humidity. This helps users assess environmental conditions more efficiently and gives the kit wider value for HVAC, facilities and indoor climate work.

The Bluetooth connection helps reduce cable clutter and gives users more freedom when working in awkward spaces or around installed equipment. The testo 440 platform also supports broader IAQ work with additional compatible probes, while onboard memory can store up to 7,500 readings and the USB interface allows data export as CSV files for reporting and analysis. Supplied in a basic case, this is a strong kit for users who want a professional, expandable humidity measurement setup.
