TSI 440 Thermo Anemometer

The Airflow™ Instruments Velocity Meter TA440 is like having multiple meters for the price of one, yet simple to operate. The TA440 includes a straight probe—all in one compact package.
Ideal applications include HVAC system performance, commissioning, plant maintenance, critical environment certification and duct traverses.

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.
