Welcome to a new era – the testo 440 combines a compact handheld measuring instrument with intuitive measurement menus and a comprehensive selection of air velocity and IAQ probes. Use it to keep all your air conditioning and ventilation needs safely and reliably under control.
Versatility in a Compact Design
- Intuitive measurement menus
The testo 440 comes programmed with clearly structured menus for volume flow, K factor, degree of turbulence, heating/cooling output, mold detection, and long-term measurement.
- Wireless convenience
All of the testo 440's probes are also available as wireless Bluetooth versions.
This makes for less cable clutter in your instrument's case.
- Clear display
View measurement configurations, readings, and results at a glance.
- Cost effective
Save money with the testo 440 – this instrument does not need to be calibrated, it measures all air velocity and IAQ parameters, and its probes can be flexibly extended.
The measuring instrument for any air conditioning application:
4 reasons why the testo 440 will make your work more efficient:
1. Intuitive – clearly structured menus, large display
Menus for measuring volume flow, K factor, and degree of turbulence in accordance with EN ISO 7730 / ASHRAE 55, heating/cooling output, mold 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; readings and results are available at a glance.
2. Wireless – available Bluetooth probes eliminate cable clutter
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 your instrument's case.
3. Space saver – 1 handle for all probes, wired or wireless
Both the Bluetooth and the cable handle available for the testo 440 can be universally combined with all the attachments in the testo 440 probe system. This means you will need less equipment, and it will take you a matter of seconds to switch from measuring comfort level to determining volume flow in ducts.
4. Money saver – a one-time investment with long-term benefits
The testo 440 air velocity & IAQ measuring instrument is an investment in smart, robust technology, which will certainly pay off:
- Suitable for all air conditioning applications – you don’t need any other measuring instruments
- Probes can be flexibly extended – lower costs for accessories and probes
- The testo 440 and testo 440 dP do not need to be calibrated – no downtimes
