Description

Measurement of all climate parameters with only one measuring device: The multi-function measuring device has an integrated differential pressure sensor and an intuitive operation with clearly structured measurement menus. Adjusting air conditioning and ventilation systems, monitoring air quality or comfort measurements – you are optimally equipped for your measuring task thanks to the versatile combination options with high-quality digital probes. Please order the probes separately!

The Testo 440 DP climate meter contains a differential pressure sensor, USB cable and calibration protocol, is delivered with inserted batteries and is immediately operational!

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.
