Digital thermo-anemometer with thermodrop and measurement of temperature, humidity, and air velocity HTA105 is designed for measuring air velocity with the option to select European or Anglo-Saxon units of measurement. The hot-wire anemometer performs measurements using a telescopic extendable probe, capable of also measuring temperature and humidity thanks to built-in sensors. Additional features include measurement of volumetric airflow (parameters CMM and CFM), as well as calculation of average values over space and time. HTA105 is equipped with MAX/MIN and Data HOLD functions, as well as internal memory for storing air velocity measurement results. It features a dual backlit display and an automatic shut-off function to conserve internal battery life.
