Environmental Measurements (Thermo-Anemometers)

HTA105 (HT Instruments)

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. It is provided with a back-lighted double display and auto power off to save internal battery life.
