0563 4410
Volume flow measurement in ducts with the air velocity and IAQ measuring instrument testo 440
Volume flow measurement at outlets with the air velocity and IAQ measuring instrument testo 440
SAR 7 999
  • Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts, at ventilation outlets and in work rooms
  • Space-saving: combine the universal Bluetooth handle with the humidity/temperature probe head or extendable telescope (1.0 m). Vane probe heads (Ø 16 mm, Ø 100 mm) can simply be plugged onto the telescope
  • Convenient: wireless probes, internal data storage and USB port for data export
  • As multifaceted as your challenges themselves: the testo 440 dP has an integrated differential pressure sensor and can be expanded with a large portfolio of digital probes
  • Carry out measurements without any annoying cables: use the kit to handle all relevant measurements in ventilation ducts and at air/ceiling outlets. You will receive the testo 440 dP air velocity and IAQ measuring instrument including differential pressure sensor, two vane probe heads (Ø 100 mm and Ø 16 mm) and a humidity/temperature probe head – all three can be attached to the universal Bluetooth® handle supplied. To make measurements more convenient, both vane probe heads can be combined with the telescope included in the kit. The equipment can be transported safely and conveniently in the robust case.

                                                                                                                                                                                                    You can even carry out easy measurements in particularly large ducts. This is because the extendable telescope on the hot wire and vane probe (Ø 16 mm) with universal handle can be further extended using the telescope extension – enabling you to attain a total length of 2 metres.

                                                                                                                                                                                                    Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit your vane probe (Ø 100 mm) with the telescope with 90° angle and, if necessary, with the telescope extension (both can be ordered separately).

                                                                                                                                                                                                    Greater freedom thanks to Bluetooth: the air velocity probes with Bluetooth have no inconvenient cable connection to the measuring instrument, and they transmit readings up to a distance of 20 m. Press the button on the probe to operate the measuring instrument – for example, to start and stop a series of measurements (timed mean calculation).

                                                                                                                                                                                                    Attach the testo 440 dP air velocity and IAQ measuring instrument to metal surfaces (e.g. ducts) easily using the practical magnets.

With its menu for recording readings, the testo 440 air velocity and IAQ measuring instrument is ideal for monitoring the indoor air quality. Enter the measurement time and the measuring cycle – and, for example, track the change in CO2 concentration or humidity and temperature values over the course of the day. Simply choose between probes with Bluetooth or fixed cable for CO2, CO or humidity (please order probes that are not included in the kit separately).

The turbulence probe (please order separately) measures air velocity and air temperature, and automatically calculates the draught risk and the degree of turbulence in accordance with EN ISO 7730/ASHRAE 55.
                                                                                                                                                                                                    For convenient measurements at varying heights, we recommend using our measuring tripod for comfort level measurement (please order separately). This makes it very easy to position turbulence probes in compliance with the standards.

                                                                                                                                                                                                    • High-precision flow measurement in fume cupboards with the fume cupboard probe
                                                                                                                                                                                                    • Thanks to the low start-up speed of 0.1 m/s, the high-precision vane probe (Ø 100 mm) is ideal for laminar flow measurements in cleanrooms. It is available as a variant with Bluetooth or with fixed cable
                                                                                                                                                                                                    • To measure the humidity in cleanrooms, we recommend the high-precision humidity/temperature probe (0636 9771 or 0636 9772). With an accuracy of ±(0.6 %RH + 0.7% of m.v.) (0 to 90 %RH), it also meets the requirements for humidity measurements in this particularly sensitive area
                                                                                                                                                                                                    • Use the high-precision digital Pt100 temperature probes, for example, for high-precision comparative measurements in calibration laboratories, temperature measurements in chemical laboratories or in the cosmetics industry as well as for determining the temperature distribution in refrigerators and conditioning cabinets
