The HT HTA105 was developed for air speed measurement. European or Anglo-Saxon measuring units are available. The hot wire anemometer takes measurements with an extendable telescopic probe, which thanks to its built-in sensors can also carry out temperature and humidity measurements. Other functions include measuring the air volume flow (CMM and CFM parameters) and calculating average values in volume and time. The HTA105 also has an internal memory that can save the measurement results of the air speed with the functions MAX / MIN and Data HOLD. It is equipped with a backlit double display and automatic switch-off to save the internal battery life.
