Intuitive climate measurement
Welcome to a new era: the 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.
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.
All the testo 440 probes are also available as wireless Bluetooth versions. This makes for less cable clutter in the measuring case.
Measurement configuration and display of readings and measurement results at a glance.
The testo 440 saves you money:
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
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.
The menus programmed into the instrument guide you efficiently through volume flow measurements in ducts and at outlets, K factor and Pitot tube measurements.
