Air movement testing, such as velocity and flow, can be critical to HVAC system balance and operation. To help measure air velocity in a variety of onsite locations, choose from our line of handheld air velocity meter and anemometer units. To help reliably and simply measure volume, choose a portable air flow hood that can effectively capture and test air from diffusers and grills. Transmitting products can provide air velocity measurements at precise flow rates and temperatures, and can be mounted in hard-to-reach places. Find all the air movement testing instruments needed for maximum heating and cooling system performance.
