TSI Airflow LCA301 Rotating Vane Anemometer Kit

The Airflow LCA301 Rotating Vane Anemometer with Aircone Flow Hood Kit from TSI Instruments is a lightweight, simple to use device that provides accurate and reliable air flow and velocity readings every time. The LCA 301 anemometer allows the user to traverse large grilles and ducts in one sweep and have the average air flow or air velocity value automatically displayed. An advanced feature of this airflow anemometer is the built-in compensation factor that helps the instrument overcome the friction of the bearings at lower velocities To ensure accuracy the LCA301 airflow measurement device has a self-diagnostic function to automatically test that the unit is working correctly. A large LCD display allows air velocity or air volume flow measurements to be quickly and clearly shown in either metric or imperial mode. This is the perfect device for HVAC commisioning at grilles, ducts and diffusers.

The TSI LCA301 airflow anemometer kit comes supplied with a square Aircone Flow Hood that can be attached to the vane sensor. This aircone hood allows for "one-shot" measurements of air volume flow at grilles, diffusers and air valves and is self sealing for leak tight readings. The hood is also suitable for measuring ventilation flow rates for both supply and extract air. Simply attach the hood and rotate the vane sensor to point into the direction of flow. The rotating vane anemometer and aircone hood are both supplied in a protective carry case for easy and safe transportation between test sites. We are also able to offer the option of an additional round Aircone Flow Hood, allowing even more flexability and suitability for certain situations.
