Contact Instrument Solutions


The TSI / Airflow LCA301 is a light weight, robust, and simple to use 100mm diameter rotating vane anemometer that provides accurate and reliable readings every time. Ideal for HVAC commissioning at grilles, ducts, and diffusers; the LCA301 displays readings in metric or imperial mode. Features include:

- Reversible 100mm head for supply and extract grills
- Calculates volumetric flow rate
- Compatible with Aircone flow hoods
- No density correction factor required
- Automatic averaging of air velocity


The LCA301 product can be supplied with an optional rectangular and circular aircone kit which turns the instrument into an air volume balancing tool.
