Welcome to a new era: the new testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a comprehensive selection of air velocity & IAQ probes. Use it to keep all your air conditioning and ventilation measurements safely and reliably under control.
Versatility in a compact design
- Intuitive measurement menus
Clearly structured menus for volume flow, K factor, degree of turbulence, heating/cooling output, mould detection and long-term measurement are programmed into the instrument.
- Wireless convenience
All the testo 440 probes are also available as wireless Bluetooth versions.
This makes for less cable clutter in the measuring case.
- Clear display
Measurement configuration and display of readings and measurement results at a glance.
- Particularly cost-effective
Save money when using the testo 440: the measuring instrument does not need to be calibrated, it measures all air velocity & IAQ parameters and the probes can be flexibly extended.
- Intuitive menus: clearly structured for volume flow-, K factor and Pitot tube measurements
- Convenient measurement: Bluetooth probes and extendable telescopes
- With a differential pressure sensor: the testo 440 dP for Pitot tube and filter measurements
- Intuitive menus: turbulence measurement in accordance with ISO EN 7730/ASHRAE 55
- Integrated long-term measurement: monitor setpoints at freely selectable measuring intervals
- A comprehensive selection of probes: turbulence, CO2, temperature, humidity, CO, lux
- Intuitive menus: clearly structured for volume flow measurement
- Special applications: high-precision probes with an unrivalled level of accuracy
- Convenient measurement: Bluetooth or cable, the right probe for any measuring location
1. Intuitive: clearly structured menus, large display H4>
Menus for measuring volume flow, K factor and degree of turbulence in accordance with EN ISO 7730/ASHRAE 55, heating/cooling output, mould detection and long-term measurement are programmed into the instrument and automatically guarantee reliable measurement results.
Measurements can easily be configured via the large display; see readings/results at a glance.
2. Wireless: probes with Bluetooth
No cables – no problems!
The Bluetooth probes for the testo 440 are available for all applications. They transfer readings to the measuring instrument wirelessly.
This guarantees greater efficiency and less cable clutter in the measuring case.
3. Saves space: 1 handle for all probes H4>
4. Economic: a one-off investment that will benefit you for a long time H4>
The testo 440 air velocity & IAQ measuring instrument is an investment in smart, robust technology, which will certainly pay off for you:
- Suitable for all air-conditioning applications – you don’t need any other measuring instruments
- Probes can be flexibly extended – lower costs for accessories/probes
- testo 440 and testo 440 dP do not need to be calibrated – no downtimes
