The TMA10A Anemometer with Flexible Precision Vane is ideal for HVAC/R technicians measuring heating, ventilation, air-conditioning, refrigeration, wind flow and temperature in residential, commercial and industrial air conditioning systems. It offers numerous functions-use it to check air velocity FPM (feet per minute), air volume (flow) CFM (Cubic feet per minute) plus the remote vane allows greater measurement location flexibility. Switch between deg C and deg F. Input the area of airflow measurement to gain accurate air velocity results. Measure an air flow source for a continuous moving average for up to two hours. Determine minimum, maximum and average readings from a single point air source. All the TMA10A measurements can be output to a computer for charting or analysis by optional model TM-SWA software and RS232 cable.
