Air Velocity Meter Model TA440
A Multi-Function, Easy-To-Operate Air Flow Meter.
SKU
TA440
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.
The TA440 Model simultaneously measures and data logs several ventilation parameters using a single probe with multiple sensors. The TA440 also measures relative humidity, and also calculates dew point and wet bulb temperature.
