testo 440 anemometer (thermocouple probe)

Kit for carrying out measurements in ventilation ducts: testo 440 anemometer, IAQ measuring instrument and thermocouple probe (Ø 9 mm) including temperature sensor, all compactly packed in a case.

Precise, reliable measurement of all air velocity and IAQ parameters with just one measuring instrument: a multi-function measuring instrument with intuitive operation and pre-saved measurement menus. Applications for adjusting air conditioning and ventilation systems, monitoring air quality or carrying out comfort measurements – thanks to the option of combining with a wide range of high-quality digital probes (optional).
