The testo 440 delta P Air Flow ComboKit 2 with Bluetooth® is a versatile, all-in-one solution for measuring air velocity, differential pressure, humidity, and temperature in ventilation ducts, air outlets, and workrooms. The kit includes the testo 440 IAQ measuring instrument, two vane probe heads (Ø 100 mm and Ø 16 mm), a humidity/temperature probe head, and a differential pressure sensor. All components are stored in a durable carrying case for easy transport.
  • Comprehensive IAQ Measurement – Measures all IAQ parameters, including flow velocity, temperature, humidity, pressure, CO2, CO, and more.
  • Integrated Measurement - enables all instruments to connect seamlessly, allowing you to capture and analyse multiple parameters.
  • Wireless Bluetooth® Convenience – No cables needed with Bluetooth® probes, allowing for flexible and hassle-free measurements.
  • Smart Data Handling – Stores up to 7500 readings and enables report exports via USB as CSV files for easy analysis.
The testo 440 delta P Air Flow ComboKit 2 with Bluetooth® is designed for professionals needing to measure a wide range of air flow and indoor climate parameters. This comprehensive kit comes with the testo 440 air velocity and IAQ measuring instrument featuring a differential pressure sensor, as well as two vane probe heads (Ø 100 mm and Ø 16 mm), a humidity/temperature probe head, and a universal Bluetooth® handle for wireless operation.

With this kit, you can accurately measure air velocity, volume flow, humidity, temperature, and differential pressure in ventilation ducts, at air outlets, and even in workrooms. The intuitive measurement menu simplifies the process, ensuring clear results and easy data collection. The vane probe heads and humidity/temperature probe head can be attached to the Bluetooth® handle and combined with the included extendable telescope (up to 1.0 m) for convenient measurements in hard-to-reach areas.

For additional flexibility, the probes can be used wirelessly via Bluetooth®, allowing for seamless operation without the need for cumbersome cables. The USB interface enables you to export measurement reports in CSV format for further analysis or documentation. All components are securely stored in a robust carrying case, making it easy to transport and keep the equipment organised.

Convenience and maximum flexibility for duct and outlet measurements

Use our large range of air velocity probes (please order probes that are not included in the kit separately) to carry out simple, convenient measurements even at locations that are difficult to access in ventilation ducts or at air outlets:

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.

Benefit from fast calculation of the volume flow: in the “volume flow” measurement menu of the multifunction measuring instrument, configure the dimensions and geometry of the duct cross-section – the measuring instrument shows you the volume flow straight away.

Long-term monitoring of indoor air quality

Poor indoor air quality due to excessive concentrations of CO2 can cause tiredness, lack of concentration and even illness. 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).

Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55

Determine the degree of turbulence and the draught risk in the workplace: draught restricts the comfort level and is the most common cause of complaints about the indoor climate. 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.

Range of probes for cleanrooms and laboratories

The testo 440 air velocity & IAQ measuring instrument is also ideal for a wide variety of applications in cleanrooms and laboratories in conjunction with the following probes:
  • 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
