- Intuitive operation: Clearly structured measurement menu for volume flow, degree of turbulence, cooling / heat output, mold growth and long-term measurements such as e.g. CO2
- Wireless: Bluetooth® probes for greater comfort when measuring and less cable tangles in the carrying case (probes can be ordered separately)
- Clear: large graphic display with simultaneous indication of 3 measured values
- Differential pressure sensor included: for Pitot tube measurements and filter monitoring
It takes just a few clicks to measure with the testo 440 dP multifunctional instrument
Wireless and space-saving: more applications with fewer tools
Convenient management of measured values
Intelligent calibration system for maximum precision


The main advantages of measuring with the testo 440 dP environmental measuring instrument
- Wide range of connectable probes: hot wire and vane probe (Ø 16 mm) for measuring in the ventilation duct; large Ø 100 mm vane probes to measure near the air vents and ceiling diffusers
- Quick calculation of the volumetric flow rate: just configure the dimensions and geometry of the duct section in the menu to view the volumetric flow directly on the display of the measuring instrument
- For effortless measurement even in large ventilation ducts. In fact, the telescopic rod of your hot wire and helix probe (Ø 16 mm) with universal handle can be extended with the additional telescopic extension and thus reach a total length of 2 meters.
- To carry out the measurements in the vicinity of the air vents and ceiling diffusers without problems and without scale. Equip your propeller probe (Ø 100 mm) equipped with telescopic rod with the 90 ° square and, if necessary, with the telescopic extension (both available separately)
- Vane probes in combination with testovent measuring funnels and detectors for measuring IN / OUT air in the vicinity of disc valves, ventilation grilles and air intakes
- Convenient Bluetooth interface: the range probes allow you to measure without the annoying cable. The measuring instrument is operated with the button on the probe handle, e.g. to start or stop a series of time averaging measurements
- The practical magnets allow a comfortable and safe fixing of the multifunction instrument on any metal surface (e.g. ventilation duct)
- The right probe for every need: The probes for CO2, CO, air temperature and humidity are available in variants with Bluetooth or with fixed cable
- Maximum ease of use: just specify the duration and interval of the measurement in the menu dedicated to long-term measurements and then follow the daily trend of the values
- Internal memory capable of containing up to 7,500 measurement protocols
- High precision even with low air speed thanks to the right degree of turbulence probe
- Automatic calculation of the risk of drafts and the degree of turbulence according to EN ISO 7730 / ASHRAE 55
- To ensure comfortable measurements and at any height, we recommend that you use our comfort analysis easel. This stand makes it particularly easy to position the turbulence degree probes in accordance with the regulations
- Probe for laboratory hoods to measure the current in the vicinity of the extractor hood with maximum precision
- Thanks to its low starting speed of just 0.1 m / s, the ultra-precise vane probe (Ø 100 mm) is the ideal solution for measuring laminar flow in clean rooms. Available in the variant with Bluetooth or with fixed cable
- Ultra-precise thermohygrometric probe (0636 9771 or 0636 9772) with an accuracy of ± (0.6% RH + 0.7% of mv) in the range from 0 to 90% RH to measure humidity in clean rooms
