TSI Airflow TA440 Air Velocity Meter – Choice of Probes
Capable of measuring an array of environmental parameters, the TSI Airflow TA440 Air Velocity Meter is a multifunctional airflow meter. It can measure air velocity and temperature simultaneously, as well as humidity, wet bulb, and dewpoint temperature. The TSI Airflow TA440 Air Velocity Meter also calculates volumetric flow, and actual/ standard velocity. Data can be logged to the TSI Airflow TA440 Air Velocity Meter’s memory (capacity for 12 700+ readings and 100 test IDs) and may be downloaded to a PC using the supplied LogDat2™ Software. Three measurements can be displayed simultaneously on the TSI Airflow TA440 Air Velocity Meter’s large, easy-to-read display.
There are two versions of the TSI Airflow TA440 Air Velocity Meter available: one with a straight probe and one with an articulated probe.
