Description
testo 440 HVAC instrument
The testo 440 combines all HVAC and indoor air quality measurements in one analyser: air velocity and flow, temperature, humidity, CO₂, CO, illuminance and comfort, thanks to a wide range of wired and Bluetooth probes. Its guided menus (duct and diffuser flow, K-factor, turbulence, cooling/heating capacity…) simplify the job and the display shows 3 values at once.
The testo 440 dP version integrates a differential pressure sensor to measure flow with a Pitot tube, monitor filters and measure the K-factor. The sets combine the instrument with the most common probes in a case.
