testo 440 CO₂ Kit with Bluetooth®
The testo 440 CO₂ Kit with Bluetooth® is the ideal solution for precise monitoring of indoor air quality. With a CO₂ probe featuring integrated temperature and humidity sensors, plus Bluetooth® connectivity and intuitive operation, this kit is perfect for facility managers, HVAC professionals, and indoor climate specialists.
- Comprehensive IAQ Measurement – Measures all IAQ parameters, including flow velocity, temperature, humidity, pressure, CO2, CO, and more.
- Wireless CO₂ Monitoring – CO₂ probe with integrated temperature and humidity sensors connects via Bluetooth® for flexible, cable-free measurements.
- Advanced Climate Metrics – Automatically calculates dew point, wet bulb temperature, and absolute humidity with absolute pressure compensation.
- Smart Data Handling – Stores up to 7500 readings and enables report exports via USB as CSV files for easy analysis.
Its clearly structured measurement menu supports long-term monitoring and offers automated calculations of important climate metrics such as dew point, wet bulb temperature, and absolute humidity. The device also compensates for absolute pressure, ensuring even greater measurement accuracy.
The CO₂ probe with Bluetooth® enhances user convenience by eliminating cables, allowing more freedom of movement during on-site evaluations. The testo 440 can be expanded with additional Bluetooth® or cable-based probes, making it a future-ready solution for various IAQ and HVAC measurement needs.
With built-in data storage (up to 7500 readings) and USB connectivity, exporting and analysing measurement reports is quick and straightforward, streamlining documentation and compliance processes.

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.

Convenience and maximum flexibility for duct and outlet measurements
With our large range of air velocity probes (please order separately), you can carry out simple and convenient measurements even at locations that are difficult to access in ventilation ducts or at air outlets:
you will even find it easy to carry out 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 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.

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
