    Dependable, Rugged Thermal Anemometers

    The dependable Airflow™ Instruments Thermal Anemometers measures air velocity and temperature, calculate flow rate and perform statistical calculations. Models are available that add a humidity measurement and perform dew point and wet bulb temperature calculations.

    Professionals have found Airflow velocity meters to be ideal face velocity meters for use in fume hoods and spray booths, or for indoor air quality (IAQ) and ventilation system checks.

    The TA410 is an economical choice for air velocity meters without compromising accuracy or precision. The TA410 features a 101.6 cm (40 in.) telescoping integrated probe for difficult to reach measurements. 

    The Models TA430 and TA440 thermal anemometers are like having multiple instruments for the price of just one. These meters simultaneously measure and data log several ventilation parameters using a single probe with multiple sensors. Both models measure velocity, temperature and calculate flow. The TA440 also measures relative humidity, and calculates dew point, and wet bulb temperature. Models TA430 and TA440 have telescopic straight probes; Models TA430-A and TA440-A have telescopic articulated probes.
