The TMA-21HV portable air velocity meter is a lightweight versatile instrument that can be used anywhere to measure air velocity, temperature and relative humidity. It can also calculate the volumetric flow rate, dew point temperature, wet bulb temperature, wind chill temperature, humidex temperature and Heat index temperature. The meter uses a telescoping probe. Applications include hood velocity, clean rooms, OSHA compliance, ventilation ducts and outlets, heating and air conditioning, wind tunnels, product development, air-flow research and mass-flow measurement in ducts. Functions includes air velocity measurement, airflow measurement, temperature and humidity measurement.
