Precision Thermal Anemometer

The TA643A High Accuracy Thermal Anemometer is a professional air velocity measurement instrument designed for accurate airflow testing, especially in low-speed airflow environments. Featuring a highly sensitive thermal sensing telescopic probe, it provides precise measurement of air velocity, air temperature, and airflow volume with a wide velocity range of 0.06 to 45.00 m/s. As a professional thermal anemometer, digital anemometer, air velocity meter, and airflow measurement instrument, the TA643A adopts a slim retractable probe design, allowing measurements in narrow spaces, inside air ducts, equipment openings, and clean environments. It is widely used for HVAC system commissioning, ventilation testing, cleanroom airflow verification, laboratory airflow measurement, fan performance testing, and industrial air circulation analysis. The instrument supports customized duct area settings and automatically calculates airflow volume, with multiple selectable units for velocity and airflow measurement. Equipped with a VA color display, built-in memory for up to 1000 data records, and USB communication capability, the TA643A enables real-time data acquisition, airflow trend analysis, and measurement report generation through computer software. With high measurement accuracy, portable design, and intelligent data management functions, this air velocity tester and airflow meter is ideal for applications in HVAC engineering, building ventilation inspection, air purification systems, electronics manufacturing, equipment cooling analysis, environmental monitoring, power plants, industrial facilities, and scientific research laboratories.
