Measure airflow and temperature simultaneously with Model VT140 Vane Thermo-Anemometer. Remote probe is designed with twisted vane arms and low friction ball bearings for accurate airflow readings in low or high velocities. Microprocessor-based unit provides fast, reliable air velocity measurement in five different scales. Model VT140 features RS232 output, selectable °F or °C, Record/Recall minimum, maximum, and average readings, display hold, and automatic shut-off to preserve battery. The large 1.4" (3.5 cm), dual function LCD with contrast adjustment allows easy viewing at any angle. Unit includes rugged holster with stand, one 9V battery, and instruction manual.

APPLICATIONS
Airflow measurements in heating, ventilation, and air conditioning systems, air duct analysis, wind tunnel studies, or monitoring of process air.
