HT Instruments HTA105 Hot Wire Digital Thermo Anemometer

Hot wire digital thermo anemometer with temperature, humidity and air speed measurement 
HTA105 was designed for air speed measurement with selection of European or Anglo-Saxon measuring units.
The hot wire anemometer carries out measurements using an extensible telescopic probe capable of taking also measurements of temperature and humidity thanks to its built-in sensors.
Additional functions include measurement of air volumetric flow rate (CMM and CFM parameters) as well as calculation of average values in space and time. HTA105 is fitted with MAX/MIN and Data HOLD function in addition to an internal memory to store air speed measuring results.

Air speed measurement with internal hot wire probe:
m/s: (0.10 ÷ 20.00); km/h (0.4 ÷ 72.0); ft/min (20 ÷ 3937); MPH (0.3 ÷ 44.7); knots (0.2 ÷ 39.0); ±(5%reading + 0.03)
Airflow measurement with internal hot wire probe:
CMM :CMM (m3/min)/ CFM: CFM (ft3 /min): 0 ÷ 99999
Air temperature measurement with internal sensor:
