The 440 moisture set is suitable for measurements in storage, cooling and working rooms, in ventilation ducts as well as at refrigeration systems and heat pumps.

The Testo 440 set contains a compact handheld meter, a humidity-temperature probe (Ø 12 mm) with Bluetooth (consisting of humidity-temperature probe head and Bluetooth handle). The Testo 440 handheld meter is delivered with inserted batteries and is immediately operational! A matching combination case is supplied as a set!

The handheld meter has a large, illuminated color display and has a structured measurement menu, displaying time and spot averaging, average volume flow, current measured value and min/max values. You can also enter the dimension and geometry of the channel cross-section to calculate an exact calculation of the volume flow. Further measurement menus such as long-term measurement and volume flow measurement with funnel are also possible.
The Testo 440 hand-held meter stores and evaluates your measurement data and can save up to 7,500 measurement protocols in its integrated measurement data memory.
Measurement protocols can be read out via a USB interface and further processed as a CSV file on the computer (e.g. with Excel).

Practical magnets are integrated in the hand-held measuring device for fixing the measuring device to metal surfaces (e.g. flow channel). An automatic detection of the probes, is available.
The enclosed humidity-temperature probe can be connected to all probe heads. The Bluetooth hand grip provides for more comfort in your measurement and less cable mess in the case!
