Product description
No more surprises: The Testo 405i thermo-anemometer with smartphone operation from the testo smart probes series is ideal for carrying out measurement tasks in ventilation ducts. It is easy to use the anemometer to determine air speed, temperature and volume flows. The testo 405i is also suitable for measuring air speed indoors. Practical if you want to find windows that are not airtight, for example. Cooling and heating outputs can also be calculated in conjunction with the testo 605i thermo-hygrometer.
